Descrição geral

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:
  • Essentially protease-free / low protease content
  • Low alkaline phosphatase content
  • Low peroxidase content

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:
  • Enzyme assays
  • Protein-based assays
  • Protease-sensitive techniques such as:
(a) Enzyme immunoassay (EIA)
(b) Nucleic acid hybridization
(c) Radioimmunoassay (RIA)

Aplicação

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.

Ações bioquímicas/fisiológicas

A albumina sérica funciona como proteína carreadora para esteroides, ácidos graxos e hormônios tiroidianos, além de ser vital na regulação das pressões osmóticas coloidais do sangue. Observa-se também que a albumina se liga a substâncias exógenas, especialmente medicamentos (p. ex., ibuprofeno, varfarina) e influencia fortemente a sua farmacocinética. O estresse oxidativo que leva a alterações no estado redox da albumina tem efeitos amplamente variados sobre a sua função fisiológica.
As albuminas são proteínas monoméricas solúveis encontradas nos fluidos e tecidos corporais de animais e em algumas sementes de plantas. A albumina sérica funciona como proteína carreadora para esteroides, ácidos graxos e hormônios tiroidianos. As albuminas séricas também são vitais na regulação das pressões osmóticas coloidais do sangue.

Características e benefícios

  • 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)
