CD45 Antibody Cocktail

SKU: orb248525

Description

This antibody cocktail contains an antibody which binds to all CD45 leukocyte common antigen (LCA) family isoforms (clone 2B11), and an antibody specific to the CD45RB isoform (clone PD7/26). CD45 is expressed on hematopoietic cell lines but absent on non-hematopoietic cell lines, normal and malignant non-hematopoietic tissues. The intracellular portions of the CD45 isoforms have protein phosphatase activity and are involved in regulation of transmembrane signals. antibody to CD45 is useful in differential diagnosis of lymphoid tumors from non-hematopoietic undifferentiated neoplasms. A positive result with this antibody cocktail is highly indicative of lymphoid or myeloid origin. Certain types of lymphoid neoplasms may lack CD45 (Hodgkin lymphoma, some T-cell lymphomas, and some leukemias) so its absence does not rule out a hematolymphoid tumor. This antibody cocktail detects CD45 expressed almost exclusively by cells of hematopoietic lineage and is present in most benign and malignant lymphocytes as well as plasma cell precursors.

Images & Validation

• Tested Applications: FACS, IHC-P, WB
• Dilution Range: Flow cytometry: 0.5-2ug/million cells,Western blot: 1-2ug/ml,Immunohistochemistry (FFPE): 0.5-1ug/ml for 30 min at RT
• Reactivity: Human
• Application Notes:
  The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the CD 45 antibody cocktail to be titered up or down for optimal performance.1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
