Tetrasodium pyrophosphate is used as a pH buffer (a substance which maintains a particular acidity level), and as a dough conditioner in soy-based "meat alternatives". It promotes binding of proteins to water, binding the soy particles together, and is used for the same purpose in chicken nuggets and imitation crab and lobster products.

Each phosphatase inhibitor component was added separately into lysis buffer to a final concentration of 25 mM β-glycerophosphate, 10 mM sodium fluoride, 10 mM sodium pyrophosphate, 1 mM okadaic acid, 1 mM sodium orthovanadate, or 1 mM sodium molybdate. Data analysis was performed using GraphPad Prism 4 (GraphPad Software).
If (as I understand) inhibits dephosphorylation of proteins....is it a good idea to include it in my cell lysis buffer especially since i am looking for phospho-proteins like Akt, ERK. I harvest my cells in PBS with activated sodium vanadate and then lyse them in the presence of protease inhibitor cocktail, sodium vanadate and NaF.
Sodium pyrophosphate tetrabasic, also called TSPP is used in the laboratory as a buffering agent. Has shown to be useful in the preparation of an EDTA-sodium pyrophosphate extraction buffer for microcystin analysis of soil samples.
A lysis buffer is a buffer solution used for the purpose of breaking open cells for use in molecular biology experiments that analyze the labile macromolecules of the cells (e.g. western blot for protein, or for DNA extraction).
Lyse is a word that comes from Greek and merely means "to split" or "to burst."Aptly, the terms pertains to what happens to cells in a lysis buffer, a solution that breaks them open to extract their contents. Scientists use lysis buffers when extracting DNA or proteins from cells for analysis, especially in the case of bacteria.
Our lysis buffers donot contain sodium phosphate and one of our buffers is similar to the second recipe that you have with lower sucrose concentration. i think sucrose is to make the solution isotonic or hypertonic. Although we use the sucrose containing buffer when we need to extract some thing for some assays.
