PB1

产品介绍 PB1 是一种有效的细胞内二硫化物还原剂,具有良好的细胞渗透性、形成高细胞内浓度梯度的能力和稳定性。PB1是一种 borane-protected TCEP (tris(2-carboxyethyl)phosphine) 类似物。在纳摩尔和皮摩尔浓度下,PB1 增加了体外轴突切开术后视网膜神经节细胞的存活。PB1 可用于神经保护的研究。
生物活性

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.

体外研究

PB1 produces a robust activation of the BDNF effector ERK1/2. PB1 promotes RGC survival.

西域 has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究

PB1 (150 μM; intraocular injection; 1 week) attenuates the loss of both RGC (retinal ganglion cells) soma and axons in experimental glaucoma.
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.
