Human CD45RA is expressed on all cells of hematopoietic origin, except erythrocytes. CD45RA is a transmembrane tyrosine phosphate which can exist in at least nine different isoforms resulting from tissue-specific alternative RNA splicing of exons 4-7 of a single gene coding for the various N-terminal peptide segments. The CD45RA isoform predominates on naive/resting T cells and medullary thymocytes. Applications: Suitable for use in Flow Cytometry and Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry: Paraffin Flow Cytometry: 5x10e5 cultured human Raji cells were incubated 45 min on ice with 80ul of anti-CD45RA antibody at 5ug/ml. Cells were washed twice and incubated with Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 1.86 log10 fluorescent units when compared to a Mouse IgG2a negative control at a similar concentration. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
