Biological Activity

Description RS-1 is a RAD51-stimulatory compound, which increases the DNA binding activity of RAD51. It is an HDR(homology-directed repair) enhancer that enhances Cas9- and TALEN-mediated knock-in efficiency in rabbit embryos both in vitro and in vivo.
Targets
RAD51 [1]
In vitro
In vitro RS-1 stimulates the binding of hRAD51 to ssDNA. Low-micromolar concentrations of this small molecule enhance DNA binding and result in longer protein–DNA complex lengths. In addition, RS-1 stabilizes the active form of hRAD51 filaments and this is reflected in an enhanced strand assimilation activity[1]. RS-1 enhances Cas9- and TALEN-mediated knock-in efficiency in rabbit embryos both in vitro and in vivo[2].
Cell Research Cell lines Early-passage neonatal human dermal fibroblasts
Concentrations 1-7.5 μM
Incubation Time 24 h
Method

Early-passage neonatal human dermal fibroblasts were maintained in Medium 106 supplemented with low serum growth supplement. Cell-survival experiments were performed using a sulforhodamine B assay. Cells are incubated for 24 h in cisplatin with or without RS-1 and are subsequently incubated for an additional 6 days in normal media lacking both agents. Sulforhodamine B-stained cells are quantified with a Synergy plate reader.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
