The amino acid sequence of human  -trace, a basic microprotein without known function, was determined by automated Edman degradations of the carboxymethylated polypeptide chain and of fragments obtained by cyanogen bromide treatment and tryptic digestion after blocking of lysine residues. The single polypeptide chain contained 120 residues, and the calculated Mr was 13,260. A proline residue at position 3 was partly hydroxylated. The presence of  -trace in a significant proportion of the cells in the anterior lobe of simian and human pituitary glands was demonstrated by immunohistochemical procedures with a rabbit antiserum against human  -trace. The tissue localization and amino acid sequence of  -trace indicated that this protein is connected with the peptidergic gastroenteropancreatic neuroendocrine system.

Flow cytometry is a technique for counting, examining and sorting microscopic particles suspended in a stream of fluid. It allows simultaneous multiparametric analysis of the physical and/or chemical characteristics of single cells flowing through an optical/electronic detection apparatus.

Yes it is. There are drugs that target the microtubule structure as well as those that act on the actin based microfilament structure.

In biochemistry, serine proteases or serine endopeptidases (newer name) are a class of peptidases (enzymes that cleave peptide bonds in proteins) that are characterised by the presence of a serine residue in the active site of the enzyme. Serine proteases are grouped into clans that share structural homology and then further subgrouped into families that share close sequence homology. The major clans found in humans include the chymotrypsin-like, the subtilisin-like, the alpha/beta hydrolase, and signal peptidase clans. Serine proteases participate in a wide range of functions in the body, including blood clotting, immunity, and inflammation, as well as contributing to digestive enzymes in both prokaryotes and eukaryotes.

Antigen is any substance that evokes the production of an antibody when introduced into the body. Antigens can enter the body through the respiratory tract, digestive tract, or skin. The most common antigens are proteins such as those found in/on bacteria and viruses.While an antibody Antibody, any of perhaps a million kinds of normally occurring protein molecules that are produced in the body of cells called lymphocytes and that act primarily as a defence against invasion by foreign substances. An important component of the immune system, antibodies are found in the blood of all vertebrates, in the fraction of the blood called gamma globulin.

Immune cells have special receptor proteins on their plasma membrane that recognize the corresponding proteins on the microorganisms.

fluorescent microscopy will work for this.  First fix the cells (3% paraformaldehyde) then permeabilize (0.5% triton-x) and then stain with antibody to your protein of interest.

Proteins are macromolecules. They are constructed from one or more unbranched chains of amino acids; that is, they are polymers. A typical protein contains 200–300 amino acids but some are much smaller (the smallest are often called peptides)\n\nWe know Proteins are Broken down from Protease and can be then broken further down into amino acids.\n\nWhy do we need Proteins for?\nWell ahve a look.\n\nMotion and locomotion of cells and organisms depends on contractile proteins. [Examples: Muscles] \nThe catalysis of all biochemical reactions is done by enzymes, which contain protein. \nThe structure of cells, and the extracellular matrix in which they are embedded, is largely made of protein. [Examples: Collagens] (Plants and many microbes depend more on carbohydrates, e.g., cellulose, for support, but these are synthesized by enzymes.) \nThe transport of materials in body fluids depends of proteins. [See Blood] \nThe receptors for hormones and other signaling molecules are proteins. \nProteins are an essential nutrient for heterotrophs. \nThe transcription factors that turn genes on and off to guide the differentiation of the cell and its later responsiveness to signals reaching it are proteins.\n\n4) Strcuture of a Protein\n\nProteins fold into a variety of 3-dimensional shapes. Experiments to unfold and refold proteins have shown that the amino acid sequence itself contains all the instructions needed for proper folding. Scientists have searched for rules governing folding but have found no reliable way to predict a 3-dimensional structure from a simple sequence.\n\nKnowing a protein's sequence does help, however. Having determined \n\n3) Importance of Proteins\nThere are proteins that build muscle, transport protein that carry nutrients, enzymes that 搄ump start?cellular activity, protein hormones involved in regulating metabolism, structural proteins like collagen, and special proteins needed for antibody production. Proteins are thus involved in all body functions, and are nessacary for health.\n\nProteins are large molecules that are made up of smaller chains of peptides. Peptides are chains of amino acids that are biochemically bonded together. There are about 50 amino acids is a single peptide chain. During normal digestion the proteins we take in are broken down into its simplest form (amino acids). These amino acids are then absorbed by the body and made back into proteins that the body needs. As we saw before proteins are crucial to a variety of body functions and structure. This is why everybody need to include protein foods in their diet\n\n\nSort of answer Your Question?

Amino acids are organic molecules with amino groups (-NH2) and acidic groups (-COOH).  When the amino group (-NH2) of one amino acid reacts with the acidic group (-COOH) of another, the bond is called a "peptide" bond (IIRC.)\n\nIf you link a small number of amino acids in this way, the product is often just called a "peptide".  The better term is "oligopeptide", as "oligo" comes from Greek, meaning "few".\n\nReally long peptides are called polypeptides or proteins.  ("poly" comes from Greek, too, meaning "many")\n\nSome proteins have different polypeptides that stick together, held by weaker forces such as electrostatic attraction.\n\nDoes that help?

Beta-2-microglobulin is a protein which occurs on the cell membranes of nucleus-containing cells and which forms as a light chain together with a heavy chain protein the so called HLA(human leucocyte antigen)class 1 Molecule.  occurance as a single protein in the serum following natural cell-death. higher in tumor growth, as rejection reaction after transplant, infections due to heightend activity of the immunsystem and progredient HIV. this parameter is tested in the urine because itm passed renally. normal 0.8-2.4 mg/l Serum

No. \nFirst of all, the endoplasmic reticulum is contained by the cells( except neuronal ones). It's job inside the cell is in the protein metabolic reactions.\nThe microsom is a genetica structure, much smaller than any other components of the cell. It helps transporting genetical information from the reticulum to other structures with the help of genes.

Basically, it is tagging the substance to be delivered to an incredibly tiny particle of gold; usually, there is an antibody (or other targeting substance) attached to the gold particle as well, to target a specific cell type or cellular structure.  It is the antibody that does the targeting; the gold nanoparticle is but the (essentially passive) tool used to carry the targeting molecule and the drug molecule.\n\nIt's one of the developing technologies--it's far from being routine, yet, last I heard.

glycoproteins are basically sugar molecules that attach to proteins in the body.  ogliosaccharides is the term i think.  anyway glycoproteins help signal the cells in the body basically to do their job and help the body to function.  people who could have a deffiency in these could suffer from a multiple of disorders or problems, one of them being hearing loss.  however this med hasnt officially been approved for this treatment, which is probably the reason in which you cannot find any research on it, and to some extent, i wouldnt believe everything i read on the web anyway.  there are places that sell them on the web, but i dont if i would go there, i would first before anything have her parents talk to her pediatrician.  i wouldnt even know if they would be safe for someone her age to take.

Biologists in microprop you say??  Well, it depends.  THere are several stages and a biologist could be responsible for any part of them.  For instance, making the callus culture and ensuring that the proper amount of plant horomones are present, to the actual studying of methods of microprop. Quality control, disease checking, all that jazz. If you want specifics, that's a lot of information but you could look up wikipedia.org, and I am sure they have anice section on microprop.  Good luck!
