Cy7 NHS Ester: Practical Labeling Guide
2026-09-21
Sulfo-Cy7 NHS Ester (SKU A8109) is a water-soluble amino-reactive dye for preparing near-infrared-labeled proteins and peptides for analytical and imaging workflows. It is most appropriate for targets with accessible primary amines and should not be treated as a universal labeling reagent or stored long-term as a solution.

Sulfo-NHS-SS-Biotin: Practical Labeling Guide
2026-09-20
Sulfo-NHS-SS-Biotin is a water-compatible, cleavable reagent for labeling primary amines on proteins and accessible cell-surface molecules before avidin or streptavidin enrichment. It is appropriate for extracellular or purified targets, but freshly prepared solutions are required and routine intracellular labeling is outside its intended use without a validated permeabilization step.

BE4 Versus ABE: Off-Target Mutations in Mouse Embryos
2026-09-16
This study used family-based whole-genome sequencing to compare cytosine base editor 4 (BE4) and adenine base editor (ABE) fidelity in mouse embryos using the same guide RNA. BE4-edited mice showed excess single-nucleotide variants and deletions, whereas ABE was comparatively precise but still produced rare site-specific C-to-T changes, emphasizing the need for editor- and target-specific validation.
