WebAvidin is a glycoprotein found in the egg white and tissues of birds, reptiles and amphibia. It contains four identical subunits having a combined mass of 67 to 68 kDa. Each subunit consists of 128 amino acids and binds one molecule of biotin; thus, a total of four biotin molecules can bind to a single avidin molecule. WebBoth avidin and streptavidin bind to biotin with high affinity, though avidin can exhibit high non-specific binding. Extravidin®-agarose uses a modified avidin with very high affinity and specificity for biotin.

WebAvidin is a homotetrameric glycoprotein found in the egg white of birds, reptiles and amphibians. Each subunit is 16 kDa, singly glycosylated and binds to a molecule of biotin … Webavidin: [noun] a protein found in egg white that inactivates biotin by combining with it.

WebIt consists of a fusion protein composed of the immunostimulatory Mycobacterium tuberculosis heat shock protein 70 (MtbHSP70) and the biotin binding protein, avidin. … WebAvidin is a tetrameric biotin-binding glycoprotein with a molecular weight of approximately 62.4 kDa. Streptavidin has identical biotin binding properties compared with avidin, but lacks the glycoprotein portion of the molecule and therefore shows less non-specific binding.

WebStreptavidin, a tetrameric 60-kDa avidin analog isolated from the bacteriumStreptomyces avidinii, is capable of binding biotin with a very high affinity—approximately 10 times higher than that of most antibodies for their antigens. The use of streptavidin is preferred to avidin for several reasons: 1. WebThe avidin-biotin system is a simple yet elegant system to link proteins in immunoassays by exploiting the very high affinity of hen egg-white avidin for biotin (vitamin B7). Streptavidin, isolated from bacteria, binds to biotin equally well but lacks the glycoprotein portion found on avidin and therefore shows less non-specific binding.
