Description of PB2

PB2 is a tris(2-carboxyethyl)phosphine (TCEP) analogue increasing retinal ganglion (RGCs) cells survival after axotomy in vitro at nanomolar and picomolar concentrations. PB2 is substantially more permeable than TCEP. PB2, as a reducing agent, is highly neuroprotective for RGCs[1].

PB2 (0.001~100000 nM; 72 hours; RGCs) increases RGC viability[1].PB2 has modifications that neutralize the polarity of the compounds. The methylesters of PB2 is likely to be cleaved by cytosolic esterases, yielding a polar intracellular intermediate that would be unlikely to cross cell membranes[1].

General tips Please select the appropriate solvent to prepare the stock solution according to the solubility of the product in different solvents; once the solution is prepared, please store it in separate packages to avoid product failure caused by repeated freezing and thawing.Storage method and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored at -20°C, please use it within 1 month.
To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time.
Shipping Condition Evaluation sample solution: shipped with blue ice. All other sizes available: with RT, or with Blue Ice upon request.

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
