Sodium chloride B7288: Buffer Prep and QC
2026-09-30
Sodium chloride B7288 is an inorganic salt for setting ionic strength and supporting osmotic balance in aqueous buffers, biochemical assays, and selected cell culture media workflows. This guide covers calculation, dissolution, storage, and QC boundaries while clarifying that it is not a pH buffer, a DMSO- or ethanol-based stock material, or a sterility-qualified reagent.

SHC-1, CFTR Trafficking, and Cell-Type Dependence
2026-09-29
Barros and colleagues show that MAPK/SHC-1-dependent CFTR internalization is detectable in airway and intestinal epithelial models, but pharmacological increases in surface CFTR are restricted to CFBE cells and are not selective for CFTR. The findings identify important model dependence in CFTR trafficking assays and support cautious evaluation of SHC-1 as a target in cystic fibrosis research and related epithelial disorders.

Shell MEAs for 3D Cardiac Organoid Electrophysiology
2026-09-29
Choi and colleagues introduced programmable, shape-adaptive shell microelectrode arrays that wrap cardiac organoids and record electrical activity across their three-dimensional geometry. The platform combines high-resolution activation mapping with calcium imaging and pharmacological perturbation, creating a practical framework for cardiac electrophysiology research and organoid-based drug response studies.

Calpain Inhibitor I, ALLN: Practical Lab Guide
2026-09-28
Calpain Inhibitor I, ALLN (SKU A2602) is a DMSO-compatible research reagent for probing calpain- and cathepsin-linked proteolysis in apoptosis assays, inflammation research, and ischemia-reperfusion injury models. It is not a calpain-only probe, and its findings should not be treated as evidence of therapeutic or diagnostic use.

EX 527 and the Causal Logic of SIRT1 in Aging Bone
2026-09-26
SIRT1 activation has been linked to improved vascular and osteogenic function in aged-bone models. This article explores how EX 527 (SEN0014196) can test whether SIRT1 catalytic activity is necessary for those phenotypes—while distinguishing target engagement, pathway readouts, and functional outcomes.

SC 79: A Practical Guide to Akt Signaling
2026-09-26
SC 79 activates Akt through a cytosolic mechanism, making it a useful perturbation tool for testing whether Akt activity contributes to stress responses—not simply a way to reproduce an upstream stimulus. This guide translates the SIRT7–AKT/mTOR findings in periodontal fibroblasts into a controlled workflow, with practical starting conditions, interpretation cautions, and troubleshooting advice.

Tricine-SDS-PAGE Gel Preparation Kit: K4136
2026-09-25
The Tricine-SDS-PAGE Electrophoresis System Gel Preparation Kit (K4136) is intended to improve separation of low-molecular-weight proteins and peptides that can be poorly resolved by conventional Tris-based SDS-PAGE. It supports research workflows, including denaturing or non-denaturing electrophoresis when the sample and running conditions are configured accordingly; it is not for diagnostic or medical use.

25-Hydroxycholesterol Reprograms TAM Immunometabolism
2026-09-23
The reference study identifies CH25H-derived 25-hydroxycholesterol as an immunometabolic checkpoint in tumor-associated macrophages. It connects lysosomal sterol sensing to AMPKα–STAT6 signaling, ARG1 production, T-cell exclusion, and resistance to immune surveillance, while suggesting that CH25H targeting can improve anti-PD-1 responses in preclinical tumor models.
