PB1 is a potent intracellular disulfide reducing agent with several advantages including good cell permeability, the ability to form a high intracellular concentration gradient, and stability. PB1 is a borane-protected TCEP (tris(2-carboxyethyl)phosphine) analogue. PB1 increases retinal ganglion cells survival after axotomy in vitro at nanomolar and picomolar concentrations. PB1 can be used for the research of neuroprotective[1][2][3].
PB1 produces a robust activation of the BDNF effector ERK1/2. PB1 promotes RGC survival[1].
PB1 (150 μM; intraocular injection; 1 week) attenuates the loss of both RGC (retinal ganglion cells) soma and axons in experimental glaucoma[1].PB1 protects RGC soma in experimental glaucoma. PB1 single dose limits the biological activity in vivo. PB1 attenuates the loss of both RGC soma and axons in experimental glaucoma. PB1 (0.001~100 μM; 72 hours) is effective at rescuing acutely axotomized retinal ganglion cells[1][2].

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
