Application
- Buffers more than buffering agent: introducing a new class of stabilizers for the protein BSA.: This research highlights the use of MOPS sodium salt as a novel stabilizing agent for bovine serum albumin (BSA), extending its role beyond a simple buffering agent. The study demonstrates how MOPS sodium salt can improve the stability of BSA under various conditions, providing significant insights for biochemical applications and protein preservation (Gupta BS et al., 2015).
