Cystine in human serum proteins.
نویسندگان
چکیده
FEW QUANTITATIVE ANALYSES of cystine in human serum protein fractions have been recorded in the literature, since cystine cannot be determined easily by microbiologic assay or paper chromatography. Brand and his coworkers (1, 2, 3) have reported the amount of cystine and cysteine in a few protein fractions using phosphotungstate and iodometric methods, but few results have been given using the sodium 1 ,2-naphthoquinone-4-sulfonate method of Sullivan (4).

The reversible binding of half-cystine residues to serum protein, and its bearing on the cystine requirement of cultured mammalian cells.
All the serially propagated mammalian cell cultures SO far examined, as well as monkey kidney cells in primary passage, have been found to require a minimum of 13 amino acids (l-4). One of the 5 amino acids regularly required in culture, but not necessary for nitrogen balance in man, was L-cystine. In many of the experiments, however, there was definite if limited initial cellular growth in a c...

Serum leucine-aminopeptidase (LAP) and cystine-aminopeptidase (CAP) determinations have been made using a chemical method based on enzymatic hydrolysis of l-leucine-/?-naphthylamide-hydrochloride and cystine-di-/?naphthylamide, respectively. Fractionation of serum proteins by gel filtration on "Sephadex-G 200" has been used for separation of LAP and CAP (oxytocinase). — CAP which appears during...

BACKGROUND Cancer is a severe threat to the human society. In the scientific community worldwide cancer remains a big challenge as there are no remedies as of now. Cancer is quite complicated as it involves multiple signalling pathways and it may be caused by genetic disorders. Various natural products and synthetic molecules have been designed to prevent cell proliferation. Peptide-based antic...

Background: Strongyloides stercoralis is prevalent in tropical and subtropical regions of the world. S. stercoralis is the only nematodes with the ability to multiply in its host's body via autoinfection transmission. Larvae detection in faeces is difficult partly because of low egg production and irregular larvae excretion in faeces. Serologic tests (ELISA, IFA) are also diagnostic, however, S...

Calcium-binding proteins play essential roles in the cell. One important class of calcium-binding proteins is the annexin family. This is a family of 13 proteins, which binds to phospholipids in a calcium-dependent manner. Osteosarcoma cell line (MG-63) is a transformed cell that has many characteristics of the differentiated cell, such as a considerable serum dependency in its growth rate. Usi...
