法规信息
What is the molecular weight of A7030, BSA?
Albumin has a molecular weight of 66,430 g/mol as a single polypeptide chain.
Is Product No. A7030, BSA fraction V?
All albumins are fraction V. Based on the fractionation of serum, fraction I is fibrinogen, fraction II is gamma-globulins, fraction III is beta-globulins, fraction IV is alpha-globulins, and fraction V is albumin.
What does "fatty acid free" mean as it relates to BSA albumin, Product A7030?
Albumin has 4 hydrophobic binding domains but the normal load is 1 to 2 molecules per molecule of albumin. The normal level of fatty acids for albumin is 0.05 % +/- 0.03 %. Fatty acid free albumin will have less than 0.005 % fatty acids.
How many lysine residues does A7030 albumin have?
Bovine albumin will have 59 lysine residues but not all of them are accessible for conjugation.
