C-Peptide, dog is a component of proinsulin, released from pancreatic beta cells into blood together with insulin. The C-peptide of proinsulin is important for the biosynthesis of insulin but has for a long time been considered to be biologically inert.

Ac2-26 TFA, an active N-terminal peptide of annexin A1 (AnxA1), attenuates ischemia-reperfusion-induced acute lung injury. Ac2-26 also decreases AnxA1 protein expression, inhibits the activation of NF-κB and MAPK pathways in the injured lung tissue.

Cy3 NHS ester 是一种 CY 染料。CY 为花菁 (Cyanine) 的缩写，是由奇数个甲基单位连接的两个氮原子组成的化合物。菁类化合物具有波长长、吸收和发射可调、消光系数高、水溶性好、合成相对简单等特点。CY 系类染料常被用于蛋白，抗体以及小分子化合物的标记，对于蛋白抗体的标记，可以通过简单的混合反应来完成结合，以下我们介绍了蛋白抗体标记的标记方法，具有一定的参考意义。
