Description générale
Albumin is the most copious protein in blood plasma. Produced in the liver, serum albumin serves as a carrier protein for biomolecules like as fatty acids, amino acids, and steroids.
This human serum albumin (HSA) product has been specially tested and evaluated to be low in the following properties:
Serum albumin is used in various applications related to molecular biology, notably as an inert protein stabilizer for stock solutions of enzymes and proteins of interest. In such applications, it is thus important for the HSA to be protease free, to maintain the integrity of the protein or enzyme of interest.
Protease-free HSA is especially useful for applications like:
(b) Nucleic acid hybridization
(c) Radioimmunoassay (RIA)

Application
Albumin was used to test its effect on the in vitro bactericidal activity of cefditoren against penicillin-resistant Streptococcus pneumonia. It has been clinically used in serious and often life-threatening conditions, such as shock and blood loss due to trauma, burns, and surgery.
It was used to test the effect of non-enzymatic glycation on the unfolding of human serum albumin. It was also used to test the two distinct pathways used by intestinal epithelial cells for HLA class II antigen processing.

Actions biochimiques/physiologiques
L′albumine sérique fonctionne en tant que protéine porteuse des stéroïdes, acides gras et hormones thyroïdes, et est essentielle à la régulation de la pression colloïde osmotique du sang. L′albumine est également capable de se lier à certaines substances exogènes, en particulier les médicaments (p. ex., ibuprofène, warfarine) et influence fortement leurs propriétés pharmacocinétiques. Le stress oxydant, qui entraîne des changements de l′état d′oxydoréduction de l′albumine, exerce des effets divers sur sa fonction physiologique.
Caractéristiques et avantages
- Low protease activity / essentially protease-free (≤ 0.0001 units/mg protein)
- Low alkaline phosphatase activity (≤ 0.001 units/mg protein)
- Low peroxidase activity (≤ 0.001 units/mg protein)
