RS-1, 10mg

A potent small-molecule stimulator of human RAD51, supplied at 10 mg per vial for laboratory use in precision genome editing workflows. RS-1 enhances homology-directed repair (HDR) in cells undergoing CRISPR-Cas9 editing, increasing knock-in efficiency and supporting accurate templated repair at targeted loci. The compound is typically reconstituted in DMSO and applied to cell cultures at working concentrations in the 1–10 µM range, making it a practical addition to gene knock-in, reporter-line construction, and isogenic control generation protocols.

This formulation from STEMCELL Technologies is packaged as a single-use vial suitable for routine HDR enhancement studies in both immortalized and primary cell models. Store the powder at room temperature, protected from light and moisture, and aliquot reconstituted stocks for frozen storage to limit freeze-thaw cycles. Each 10 mg unit provides ample material for multiple editing experiments, and the compound is intended for research use only, supporting in vitro applications including stem cell engineering, disease modeling, and functional genomics screens.
