生物活性

製品説明 RI-1 (RAD51 inhibitor 1) is a RAD51 inhibitor with IC50 ranging from 5 to 30 μM.
in vitro RI-1 sensitizes cells to DNA damage by directly and specifically disrupting HsRAD51 and inhibiting the ability of RAD51 to form filaments on ssDNA. In addition, RI-1 alone generates single-agent toxicity in all three cancer cell lines (HeLa, MCF-7 and U2OS) with LD50 values in the 20–40 µM range. [1] RI-1 decreases the rejoining of γ-H2AX foci in G2 phase cells and results in a higher level of unrepaired DSBs 6 hours after irradiation. [2]
特徴 A selective recombinant RAD51 protein inhibitor discovered in 2012. Valuable tool for mechanistic studies of DNA repair and potential for use in many cancers.

キナーゼアッセイ DNA binding assays
All reactions are performed in black non-binding polystyrene 384-well plates with reaction volumes of 30–100 μL. Purified DNA strand exchange proteins and chemical compounds are pre-incubated at room temperature for 5 minutes; they are then further incubated at 37°C for 30 min with 100 nM of ssDNA substrate, consisting of a 45-mer poly-dT tagged with Alexa 488 at the 5’ terminus (synthesized and purified by Integrated DNA Technologies). Reactions are performed in 20 mM HEPES pH 7.5, 10 mM MgCl2, 0.25 μM BSA, 2% glycerol, 30 mM NaCl, 4% DMSO and 2 mM ATP. Some conditions included DTT or TCEP (tris(2-carboxyethyl)phosphine) as indicated. DNA binding is measured as a function of fluorescence polarization (FP) with a Safire2 plate reader, using the following settings: excitation 470±5nm, emission 530±5nm, 10 reads/well, Z height and G factor auto-calibrated from control wells. Displayed error bars represent standard deviation. For experiments involving a titration of protein concentrations, data are fit to an equation that accounts for the cooperative nature by which recombinase proteins bind DNA. For experiments involving a titration of RI-1, protein concentrations are selected to give an ∼80% saturation of the FP signal in the absence of RI-1.
細胞アッセイ 細胞株 HeLa, MCF-7 and U2OS cells
濃度 ~35 μM
反応時間 24 hours
実験の流れ Cytotoxicity is determined by loss of colony-forming ability. Experiments are performed in triplicate. Crystal violet stained colonies are imaged with a CCD camera and counted using NIH Image software. Error bars denote standard error.
