Apoferritin is the Protein shell of ferritin. Calibration of gel filtration columns and sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis Acts as an anti-oxidant When added to cultured endothelial cells apoferritin is taken up in a dose-responsive manner and appears to…

Lectins are proteins or glycoproteins of non-immune origin that agglutinate cells and/or precipitate complex carbohydrates. Lectins are capable of binding glycoproteins even in presence of various detergents. The agglutination activity of these highly specific carbohydrate-binding molecules is…

Avidin is a basic glycoprotein consisting of four essentially identical subunits. The combined molecular weight of the subunits is about 66,000. Each subunit is a single polypeptide chain containing 128 amino acid residues with alanine at the N-terminal, glutamic acid at the C-terminal, and a…

Arginine-rich subgroup. Commonly used for chromosome-reconstitution studies. Suitable substrate for protein kinase C.

Avidin is a basic glycoprotein isolated from raw egg white. It exhibits high binding affinity for biotin and is capable of producing biotin deficiency in rats and chicks. It also occurs in the white portion of eggs and the oviducts of birds and amphibia. It is destroyed by cooking or irradiation. …
