RN277
Based on 1 Customer Validation
RN277 is a selective LRRK2 inhibitor with an IC50 of 135 nM against LRRK2RCKW kinase. RN277 inhibits LRRK2-mediated phosphorylation of Rab8a. RN277 rescues the motor activity of kinesin inhibited by LRRK2RCKW in vitro, and its mechanism of action may involve preventing LRRK2 from forming filamentous structures on microtubules. RN277 can be used in studies related to Parkinson's disease.

製品説明
体外実験
RN277 (4 h) inhibits LRRK2RCKW-mediated phosphorylation of its physiological substrate Rab8a in vitro, with an IC50 of 70 nM[1].
RN277 (0.25-5 µM; 4 h) dose-dependently inhibits LRRK2-mediated Rab8a phosphorylation in 293T cells, reducing the phosphorylation level to near background at 5 µM, without affecting the S935 phosphorylation of LRRK2[1].
RN277 (5 µM; 10 min pre-incubation with LRRK2RCKW, 5 min incubation with microtubules) restores the microtubule motility of K560-GFP kinesin inhibited by LRRK2RCKW[1].

Kinase activity and phosphorylation assays
Kinase activity assays measure the ability of kinases to transfer phosphate groups from ATP to specific substrates, while phosphorylation assays detect the presence and levels of phosphorylated proteins. Common methods include radiolabeled ATP incorporation (e. g. ,), ADP release detection via bioluminescence (e. g. ,[3]), enzyme-linked immunosorbent assays (ELISA) for phospho-specific epitopes (e. g. ,[6]), and microtiter-based formats for high-throughput screening (e. g. ,[8]). The ADP-Glo assay quantifies kinase activity by measuring ADP produced during phosphorylation using a luciferase-based system. Radiometric assays involve autoradiography or scintillation counting after incorporation of 32P-labeled ATP into substrate proteins. ELISA-based approaches rely on phospho-specific antibodies to detect activated kinases in cell lysates or purified samples.

Western Blot
Western blotting (WB) is a commonly used experimental method in molecular biology, biochemistry, and immunogenetics for identifying and quantifying target proteins. It combines gel electrophoresis with immunoassay, enabling researchers to analyze protein expression, post-translational modifications, and molecular weight.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Human pluripotent stem cell midbrain dopaminergic neuron differentiation
Human pluripotent stem cells are directed toward midbrain dopaminergic neurons by first inducing a neural floor-plate-like progenitor state, then patterning cells with ventralizing SHH signaling and midbrain/WNT-FGF cues, and finally maturing progenitors into neurons expressing dopaminergic markers such as TH, NURR1/NR4A2, PITX3, DAT/SLC6A3, VMAT2/SLC18A2, GIRK2/KCNJ6, FOXA2, LMX1A, and EN1. The main readouts are loss of pluripotency, acquisition of FOXA2+/LMX1A+ midbrain floor-plate progenitors, emergence of βIII-tubulin+/MAP2+ neurons, and production of TH+ dopaminergic neurons with molecular, dopamine-release, and electrophysiological features of midbrain dopaminergic identity.

Protocol for Kinase activity and phosphorylation assays
Kinase activity assays measure transfer of phosphate from ATP to a protein or peptide substrate, generating phosphorylated substrate, ADP, or incorporated radiolabeled phosphate as the readout; phosphorylation assays measure site-specific phosphorylation in cells or tissues as a proxy for kinase-pathway activation, inhibition, or substrate regulation. Phosphorylation can be detected by phospho-specific Western blot, immunoprecipitation kinase assay, phospho-immunofluorescence, phospho-flow cytometry, luminescent ADP detection, radiolabeled ATP incorporation, or reporter-based pathway assays, and these readouts can be applied to cancer cells, primary neurons, mouse tumors, organoids, inflammatory macrophages, ferroptosis studies, and mitophagy studies when the kinase target is biologically relevant.
