can u tell me the defintion for marker protein?

Marker proteins are proteins that you use to determine if their is active transcription of another protein. Say for example. You wanted to see if your gene you inserted into the organism is working or present. What you do is also insert a marker gene into the same plasmid. i.e. Green fluorescent protein, or an antibiotic resistance gene. So you know your gene that you inserted is working by the green glow of the gfp.

Acute-phase proteins are a class of proteins that are synthetized in the liver in response to inflammation. This response is called the acute-phase reaction

Yes proteins are amphoteric, they do contain both acidic and basic residues, but the charge on the protein is dependent on the degree of dissociation of the acidic or basic groups. \n\nThe Tris-HCl buffer used in gel electrophoresis(assuming you are talking about PAGE, most commonly used for proteins) has a pH of 8.7. At this pH the protein molecules have a net negative charge, hence they move towards the positive electrode. Their difference in mass leads to their separation as does the amount o charge that they carry.\n\nIsoelectric focusing uses the amphoteric nature of proteins to the max - it uses the isoelectric point of the protein for its separation. The isoelectric point is the pH at which the protein has no charge and hence it stops moving in the electric field.

Do you have looked PubMed? "http://www.ncbi.nlm.nih.gov" There are 36 article for serum albumin and dansyly glycine. Maybe you can try to find it experimentally.

I've never heard the term "polypeptide phrase" before, maybe they mean "polypeptide chain"? That's just a string of amino acids. It would help if you actually had the example in the question, then I could help better.

this antibody detects an ~67 kDa protein corresponding to the expected molecular mass of estrogen receptor (ER) on SDS-PAGE immunoblots. This antibody recognizes native estrogen receptor in the activated 4S or inactive 8S oligomeric state, with or without ligand binding. The antibody also recognizes a smaller molecular weight protein (~55 kDa) believed to be the major proteolytic fragment of the estrogen receptor alpha protein\n\nhard question even harder answer good luck!

"C" proteins is the correct answer.

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.

There are proteins of animal provenience, that are called also nobble proteins. They asimilate better than the others(I mean of herbal provenience). I aggree that you have to check out the pyramid of nutrition. Go to www.usda.gov, for example and do your search. Another important point that you have to check out, is the DRD(daily recommended dose),\nthat is how much do you need to take every day and how much contains each portion.\n\nKaterina
