Overview
CD45R, also designated CD45 and PTPRC, has been identified as a transmembrane glycoprotein, broadly expressed among hematopoietic cells. Multiple isoforms of CD45R are distributed throughout the immune system according to cell type. These isoforms arise because of alternative splicing of exons 4, 5, and 6. The corresponding protein domains are characterized by the binding of monoclonal antibodies specific for CD45RA (exon 4), CD45RB (exon 5), CD45RC (exon 6) and CD45RO (exons 4 to 6 spliced out). The variation in these isoforms is localized to the extracellular domain of CD45R, while the intracellular domain is conserved. CD45R functions as a phosphor-tyrosine phosphatase. antibody to CD45R is useful in differential diagnosis of lymphoid tumors from non-hematopoietic undifferentiated neoplasms.
This anti-CD45RB antibody is supplied as PE Conjugate (Mouse, Monoclonal (mouse origin), clone BRA-11, Mouse IgG1, kappa, PE) and is designed to support common target-detection workflows after the on-page specifications.

Because antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.
Biological background
CD45RB is referenced in public gene/protein resources (e.g., UniProt and NCBI Gene), which provide curated names/synonyms, protein features, and pathway context. When designing assays, consider potential isoforms, post-translational modifications, and cell-type specific expression that may influence observed signal.
Research relevance and current trends
- Profiling CD45RB expression across model systems, perturbations, and time points to support mechanistic hypotheses.
- Combining antibody-based detection with multi-omics or imaging readouts to link CD45RB signal with phenotype.
- Using well-matched controls (isotype controls, genetic perturbations, or independent reagents) to strengthen interpretation of target-associated signal.
Common research applications
- FACS
Use the listed applications as a starting point and tailor experimental design to your sample type and readout requirements.
Notes for experimental interpretation
- Specificity considerations: closely related family members, isoforms, or PTMs can affect apparent specificity; confirm with independent approaches when critical.
- Controls: include negative controls and, when feasible, genetic or pharmacologic perturbations to support target attribution in your system.
- Species and sample context: differences in sequence, expression, fixation, or extraction conditions can change signal behavior across models.
