一般描述
牛血清白蛋白（BSA）是一种球状，α螺旋状，非糖基化的蛋白质，在肝脏中产生。它由三个同源的，结构上不同的结构域和两个亚结构域组成。BSA具有17个交联并结合成单链的半胱氨酸残基。
应用
使用牛血清白蛋白组分V，不含蛋白酶：
- 用于稳定纯化的酶
- 用于ELISA技术中的位点阻断试剂
- 作为测定蛋白质浓度的蛋白质标准品
生化/生理作用
牛血清白蛋白（BSA）可促进药物、激素和脂肪酸的传输。它是酶联免疫吸附试验（ELISA）中最常用的封闭剂。BSA可增强人胚胎干细胞（hESC）的分化，也是细胞培养基的主要成分。

A family of 40 mammalian voltage-gated potassium (Kv) channels control membrane excitability in electrically excitable cells. The contribution of individual Kv channel types to electrophysiological signaling has been difficult to assign, as few selective inhibitors exist for individual Kv subunits.

Saturated fatty acids like palmitate contribute to muscle atrophy in a number of conditions (e.g., type II diabetes) by altering insulin signaling. Akt is a key modulator of protein balance that inhibits the FoxO transcription factors (e.g., FoxO3) which selectively

Allosteric ligands modulate protein activity by altering the energy landscape of conformational space in ligand-protein complexes. Here we investigate how ligand binding to a K+ channel's voltage sensor allosterically modulates opening of its K+-conductive pore. The tarantula venom peptide guangxitoxin-1E
