What is the defination of a "protein marker"?

the only protien marker that I know of has to do with anatomy

If you know that the structure of the hormone is already known, then the SciFinder is best.  If you are talking about original research, then you must get your hands on enough of the pure hormone to analyze.\nMost hormones are small (relatively speaking) proteins.  The pure hormone specimen is usually placed into a sequential analyzer and the primary structure is determined first.  The secondary structure usually requires some sort of crystallography technique.

you're very correct in that you should mention those things. some other proteins you could mention is albumin and if you don't have enough, the pressure will be different in your Extracellular Fluid, also if you don't have the right amount of proteins your cells won't be able to do protein synthesis and divide....

Urine protein determinations are semi-quantitative and are achieved via error of pH indicators and is read by a process called colorimetric refractility determination.  Urine glucose is usually seni-quantitative but can be done in quantitative fassion as well.  The semi-quantitative methode uses glucose oxidase reagent and is read via colorimetric determination.  The quantitative methode also uses glucose oxidate reagent but is read via light impeedance of a spectrophotometer.

Are you looking at any protein in particular?  Look up in situ hybrdization for proteins ( at least it will give you an idea where it is localised).  I think that it would really depend on the system ad proteins that you want to study, so I am not sure how much else I can tell you, sorry.

These are all indicators in the blood of infection or inflammation due to infection.  CRP and IGA are proteins, IGG is an antibodies that indicate the presence of an infection.\n\nCRP is a protein found in the blood. It is a marker for inflammation, meaning its presence indicates a heightened state of inflammation in the body. Inflammation is a normal response to many physical states including fever, injury and infection, and is now believed to play a role in the initiation and progression of cardiovascular disease.\n\nIGA:A type of immunoglobulin present in blood and body secretions which may aid in fighting infections.\n\nIGG: One of many antibodies present in blood serum which is usually indicative of a recent or remote infection. IgG is most prevalent about 3 weeks after an infection begins.

Generally polyclonal anitbodies are used to bind non-specifically to antigens. For instance, you might use monoclonal antibodies to specifically bind to your protein of intererst. You might then use polyclonal Ab to bind the rest of the proteins i.e. to block off the other available 'slots'

The biuret reaction is a method that can be used to determine the amount of soluble protein in a solution. The biuret reagent (copper sulfate in a strong base) reacts with peptide bonds and changes color when it does so. The spectrophotometer can then be used the measure the intensity of the color produced. The more protein present the darker the color.

Use a Bradford assay for protein. This uses a dye which goes from red to blue when it binds to proteins, and the colour change and hence the amount of protein present cana be assessed spectrophotometrically. This is a cheap, sensitive method and will give you a quantitative answer (providing you calibrate your spectrophotometer first using a standard curve produced with solutions of different known protein concentrations). This link will tell you more about the exact method.\n\nhttp://www-class.unl.edu/biochem/protein_assay/bradford_assay.htm

Western blot is a method for detecting specific proteins of interest within a specimin. Antibodies are used to specifically probe for and bind to these proteins of interest and so the method is also known as Immunoblotting. \n\nSouthern blot, named after Edwin Southern, is a method for detecting specific sequences of DNA. Complementary DNA sequences are used to probe for and bind to the DNA sequence of interest. The probed sequence is then hybridized for the purpose of visualization.\n\nNorthern blotting is much like Southern blotting as far as protocol, however this is the method used to detect levels of RNA expression, rather than DNA.\n\nHope this helps.

Not sure what type of sensitivity you are requesting?\n\nIf you need a marker, you could just incorporate a vector. If you're asking which would die first, then the smallest (can't remember their common sizes) would be the first to die; theoretically. Although, this is propably such a small difference that it would be very difficult to measure in reality.

Go to "protein" on wikipedia ( put, protein, in address bar ) then scroll down to "synthesis", for the process. It is too  long a story for my typing skills. The wiki article is not too technical.

A C-reactive protein(globulin) is a protein that is found in people who have inflammatory, degenerative and neoplastic diseases. (It shows up with long-term low-grade inflammation) A high level predicts stroke and atherosclerosis(hardening of the arteries due to cholesterol)

label the known protein with a radioactive isotope, or better yet, maybe you could label the protein with a flourescent dye (dont know how, its beyond my expertise) and where ever the protein binds on the receptive cell may be what you're looking for.  but i dont know of any assays per se for it.

I am not sure what you are asking.  AP?  Alkaline phosphatase?  SDS-PAGE - Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis?\nSDS-PAGE separes proteins according to their sizes.  Large proteins migrate slower than small proteins.  Once the proteins are separated, a size marker next to the protein can identify its size.  Western-blot can be used to detect the protein with antibodies that recognizes the protein.  There are also antibodies that recognize phosphorylated form of the protein.

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.
