Cy7 NHS Ester: Practical Labeling and QC Guide
2026-09-27
Sulfo-Cy7 NHS Ester provides a water-soluble near-infrared label for attaching a fluorescent reporter to accessible amino groups on proteins and peptides, including samples for in vitro or in vivo imaging workflows. It is not a substitute for a cell-permeant stain, and it should not be used when the biomolecule cannot tolerate amine modification or when a stored aqueous dye solution is required.

HyperFluor 488 Goat Anti-Rabbit IgG: Use Guide
2026-09-24
HyperFluor™ 488 Goat Anti-Rabbit IgG (H+L) Antibody is a fluorescent secondary reagent for detecting rabbit primary antibodies in fluorescence-based assays. Use it in validated immunofluorescence, microscopy, or flow cytometry workflows; do not assume it is suitable for non-rabbit primaries or unmodified live-cell staining.

RNF166–Angiomotin Signaling in Colorectal Cancer
2026-09-21
The reference study identifies RNF166 as an E3 ubiquitin ligase that recognizes poly-ADP-ribosylated angiomotins and promotes their destabilization, thereby activating YAP and accelerating colorectal cancer progression. Its identification of the RNF166 Di19-ZF region as a previously underappreciated poly-ADP-ribose-binding module provides a mechanistic link between tankyrase modification, Hippo pathway control, and tumor biology.

HyperFluor 488 Goat Anti-Rabbit IgG Guide
2026-09-19
HyperFluor 488 Goat Anti-Rabbit IgG is a fluorescent secondary antibody for detecting rabbit primary antibodies in immunofluorescence, immunocytochemistry, flow cytometry, and related microscopy workflows. It should not be treated as a universal reagent for non-rabbit primary antibodies or for protocols that require azide-free or glycerol-free components without compatibility testing.

LSKL, THBS1/PI3K/AKT in PCOS Oxidative Stress
2026-09-18
A recent Life Sciences study identifies THBS1 as a mechanistic link between dehydroepiandrosterone-induced granulosa-cell injury, oxidative stress, and apoptosis in a rat model of polycystic ovary syndrome. Its combined molecular docking, cellular, and animal experiments suggest that LSKL protects ovarian function by suppressing THBS1 and restoring PI3K/AKT pathway activity.
