ある種の立体配座の一次配列を持つBSAエピトープは、ヒトの牛肉、牛乳アレルギーのアレルゲンである疑いがあります。
Bovine Serum Albumin (BSA) displays intrinsic fluorescence due to the presence of two tryptophan residues. It is widely used in ligand interaction studies and in the delivery of drugs and antibodies. BSA is used as a blocking agent in enzyme-linked immunosorbent assay (ELISA).
Preparation Note
ヒートショック分画法を用いて調製
血清アルブミンはフラクション（画分）Vと呼ばれる場合があります。この命名規則は、冷エタノール沈殿を用いて血清タンパク質を分画するオリジナルのCohn（コーン）法から取られています。血清アルブミンは、Cohn法を用いて第5エタノール画分に認められました。それ以来、「フラクションV」という用語は、調製の方法に関係なく血清アルブミンを記述するのに使用されています。他の人はこの用語を使用して、オリジナルのCohn法が記述されて以降大幅に改変されたエタノール分画法により精製された血清アルブミンのことを記述しています。Sigma-Aldrichは、真のCohn分画法、改変エタノール分画法、熱ショックやクロマトグラフィーなど様々な主要方法で精製された血清アルブミンを製造および販売しています。さらなる精製ステップには、結晶化や活性炭ろ過が含まれる場合があります。
Derived from New Zealand source serum
Application
Bovine Serum Albumin has been used:
- as a component of blocking solution used for fixing Drosophila embryos in immunostaining
- to block 96-deep-well plates in phage immunoprecipitation studies
- as a standard solution in fluorescence spectroscopy studies
General description
Bovine Serum Albumin has three homologous domains (I, II, and III) that are connected by disulfide bonds. BSA shares structural homology with human serum albumin (HSA).

siRNA brings hope for cancer therapy. However, there are many obstacles for application of siRNA in clinical. Because of the excellent biocompatibility, non-toxicity and non-immunogenicity of bovine serum albumin (BSA), BSA-based nanoparticles have been widely designed as a drug carrier

In healthy individuals, injured tissues rapidly repair themselves following damage. Within a healing skin wound, recruited inflammatory cells release a multitude of bacteriocidal factors, including reactive oxygen species (ROS), to eliminate invading pathogens. Paradoxically, while these highly reactive ROS confer

The dual oxidase-thiocyanate-lactoperoxidase (Duox/SCN(-)/LPO) system generates the microbicidal oxidant hypothiocyanite in the airway surface liquid by using LPO, thiocyanate, and Duox-derived hydrogen peroxide released from the apical surface of the airway epithelium. This system is effective against several microorganisms that
