CD44 is a transmembrane glycoprotein that serves as the principal cell surface receptor for hyaluronate, playing essential roles in cell adhesion, migration, and lymphocyte homing. This multifunctional molecule participates in diverse biological processes including immune cell trafficking, wound healing, and tumor metastasis, making it a critical target for researchers investigating immunology, cancer biology, and inflammatory diseases.
This recombinant monoclonal antibody, clone 4B7, offers the reproducibility and consistency that demanding experimental workflows require. Produced using recombinant technology in a rabbit host, this antibody provides sequence-defined specificity against human CD44, ensuring that results remain comparable across experiments and over time. The affinity-chromatography purification process delivers a reagent with minimal background interference.
Validation studies demonstrate reliable performance across multiple applications. In western blot analysis, the antibody successfully detects CD44 at the predicted molecular weight of 82 kDa across several human cell lines, including HeLa, HepG2, and A549, at working dilutions between 1:500 and 1:5000. This detection across cervical carcinoma, hepatocellular carcinoma, and lung adenocarcinoma cell lines reflects CD44's widespread expression in epithelial and cancer cells. For immunohistochemistry applications, testing in paraffin-embedded human tonsil tissue confirms the antibody's utility for tissue-based studies, with recommended dilutions ranging from 1:50 to 1:500. The antibody is also validated for ELISA applications.
Supplied in a glycerol-containing buffer optimized for long-term stability at -20°C or -80°C, this unconjugated antibody provides flexibility for researchers studying CD44's roles in immune regulation, tumor progression, and cell-matrix interactions.
