CRKL serves as a critical adaptor protein in signal transduction pathways, functioning downstream of receptor and non-receptor tyrosine kinases. As a key substrate of the BCR-ABL fusion oncoprotein, CRKL plays a particularly important role in chronic myelogenous leukemia research, where its phosphorylation status serves as a biomarker for BCR-ABL kinase activity. Beyond oncology, CRKL participates in cytoskeletal reorganization, cell adhesion, and migration processes, making it relevant to studies spanning cancer biology, developmental research, and cellular signaling.
This recombinant monoclonal antibody, clone 4B2, offers the reproducibility and consistency that demanding research requires. Because it is produced from a defined sequence in a controlled expression system, you can expect uniform performance across experiments and over time, eliminating the lot-to-lot variability that can complicate long-term studies or multi-site collaborations.
Validation by western blot demonstrates reliable CRKL detection across a diverse panel of human cell lines, including K562 chronic myelogenous leukemia cells, LO2 hepatocytes, HEK293T embryonic kidney cells, and the colorectal adenocarcinoma lines HT-29 and COLO-205. The antibody performs well at dilutions between 1:500 and 1:2000, providing flexibility to optimize signal intensity for your specific experimental conditions. The observed band at approximately 37 kDa runs slightly higher than the predicted 34 kDa molecular weight, which likely reflects post-translational modifications such as phosphorylation that are characteristic of CRKL in actively signaling cells.
Whether you are investigating BCR-ABL signaling in leukemia models, studying adaptor protein function in normal cellular processes, or exploring CRKL's role in cell migration and adhesion, this antibody provides a dependable tool for your western blot and ELISA workflows.
