H2S Persulfidation and Ferroptosis in NSCLC
2026-09-18
Zheng et al. identify hydrogen sulfide-mediated persulfidation of S-adenosyl homocysteine hydrolase as a metabolic mechanism that sensitizes non-small cell lung cancer cells to ferroptosis under cystine-limited conditions. The study connects altered homocysteine metabolism with depletion of cysteine and glutathione, providing a mechanistic rationale for combining hydrogen sulfide activity with ferroptosis-based treatment strategies.

TBST Buffer: Practical Immunoassay Workflow
2026-09-15
TBST (Tris-Buffered Saline and Tween 20) is a buffered washing and blocking solution for reducing nonspecific binding and background in antibody-based assays. It is appropriate for Western blotting, immunofluorescence, immunohistochemistry, and immunocytochemistry, but should be evaluated or avoided when non-ionic detergents may disrupt the assay or specimen.
