Product Overview
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitosis, and oncogenic transformation. This PTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus is classified as a receptor type PTP. This PTP has been shown to be an essential regulator of T- and B-cell antigen receptor signaling. It functions through either direct interaction with components of the antigen receptor complexes, or by activating various Src family kinases required for the antigen receptor signaling.

The recommended starting dilution for Western Blot is WB 1:500-1:2000;IHC 1:50-300. Optimal dilution should be determined empirically for each laboratory setup, sample type, and detection system. Use freshly prepared lysates with protease inhibitors; add phosphatase inhibitors if studying phosphorylation-dependent forms of CD45. Expected band size: Calculated 147kDa, Observed 147kDa. If background is high, increase blocking (5% non-fat milk or BSA in TBST) and/or increase wash stringency.
For IHC-P, heat-induced epitope retrieval (HIER) is typically required. Recommended starting conditions: citrate buffer pH 6.0 (microwave or pressure cooker, ~20 min) for rodent samples; EDTA buffer pH 9.0 for human clinical samples. After retrieval, allow sections to cool gradually before proceeding to blocking. Include a CD45-positive tissue control (confirmed by literature or database expression data) and a negative isotype control in every run. Recommended dilution: WB 1:500-1:2000;IHC 1:50-300. Refer to the product datasheet for any target-specific retrieval guidance.
This antibody has been experimentally validated in: Human. Cross-reactivity with other species has not been systematically evaluated. If your sample species is not listed, assess immunogen sequence homology to your target species ortholog. The immunogen used is: "Synthetic Peptide" — higher sequence identity between species increases the probability of cross-reactivity, but experimental validation with appropriate controls is necessary before drawing scientific conclusions.
Store at -20℃ Valid for 12 months. Avoid freeze / thaw cycles. Storage Buffer: PBS with 0.02% sodium azide and 50% glycerol pH 7.4.. To maintain antibody activity, avoid repeated freeze-thaw cycles. Aliquot into single-use volumes before first freeze. If working with the antibody frequently, keep a working stock at 4°C for up to 4 weeks — add 0.02% sodium azide to the working stock as a bacteriostatic agent if azide is not already present in the buffer. Monitor performance against a validated positive control when transitioning between storage aliquots or lots.
This monoclonal antibody (clone Clone:3H3) provides highly consistent, epitope-specific recognition of CD45, making it ideal for quantitative assays, multiplex panels, and studies requiring strict reproducibility across experiments and independent laboratories. Unlike polyclonal preparations, each production batch from a single hybridoma clone generates antibody with identical epitope specificity, affinity, and isotype — ensuring reliable signal comparison in longitudinal studies or multi-site collaborations. When citing this antibody in publications, include the clone designation (clone Clone:3H3) to enable third-party reproducibility verification.
Customization & Add-ons: Can't find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
