Product Description

AlbumiNZ™低内毒素牛血清白蛋白由新西兰来源牛血清通过符合ISO质量体系的色谱层析法纯化获得，确保完整的可溯性和始终如一的高质量，具有极低的内毒素含量和极低的IgG水平，可简化下游纯化。按照9CFR（《美国联邦法规汇编》第9卷）要求进行无病毒检测，达到极高的生物安全水平。该款BSA可支持干细胞的生长和增加杂交瘤细胞的蛋白产量。

利用色谱层析法纯化得到
血源可自主控制
ISO9001：2008和cGMP认证
单批次产量可达240kg
认证的供应链
可提供液体或粉末包装形式

高细胞滴度
不同批次的高一致性
完全的可追踪性

Background_information	Albumins are a group of acidic proteins which occur in the body fluids and tissues of mammals and in some plant seeds. Serum and plasma albumin is carbohydrate-free and comprises 55-62% of the protein present. However, only about 40% of the total albumin in the body is in the circulating plasma at one time with the remainder being in extracellular spaces with which there is, in general, equilibration about every 24 hours.
Base Catalog Number	199896
Biochemical Physiological Actions	Albumin loses its helical structure rapidly in 2-4 M urea and 4 M guanidinium chloride. The unfolding is reversible, even, to some extent, after concomitant reduction of all disulfide bonds . Reduced albumin can reform into structures capable of binding antibodies and other ligands . Formation of SS bonds is rapid but the return of native structure is slow and some wrong disulfide pairings may persist . After oxidation of the cystine bridges, however, native structure is irreversibly lost.
CAS #	9048-46-8
Concentration	Total Protein: ≥95%
EC Number	232-936-2
Format	Lyophilized powder
Grade	Cell Culture Grade, ImmunoAssay (EIA) Grade
Host	Bovine
Molecular Weight	66KDa

Protein or Enzyme Type	Albumin
Purity	≥97% Total Protein
Solubility	Albumins are readily soluble in water and can only be precipitated by high concentrations of neutral salts such as ammonium sulfate. The solution stability of albumin is very good (especially if the solutions are stored aliquoted and frozen). Albumin is readily coagulated by heat. When heated to 50 °C or above, albumin quite rapidly forms hydrophobic aggregates which do not revert to monomers upon cooling. Dissolves completely in 20 min at 20-25 °C (20%).
