Human CD13 is a zinc-binding aminopeptidase-N enzyme expressed on the surface of myeloid cells. IL-4 will upregulate expression of CD13 which may play an anti-inflammatory role.
Applications:
Suitable for use in Flow Cytometry and Immunohistochemistry. Other applications not tested.
Recommended Dilution:
Immunohistochemistry: Formalin-fixed paraffin sections
Flow Cytometry: 10ug/ml labels 5x10e5 ficoll prepared human
Optimal dilutions to be determined by the researcher.
Flow Cytometry Protocol:
1. Five x 10e5 cultured ficoll prepared human peripheral blood mononuclear cells were washed and preincubated 5min with 20ul human IgG (to block non-specific binding) after which they were incubated 45 min on ice with 80ul of C2264-02C at 10ug/ml.
2. Cells were washed twice and incubated with Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed by FACS.
3. A net 5% subpopulation of the cells stained positive with a mean shift of 1.53 log10 fluorescent units when compared to a Mouse IgG2a negative control at a similar concentration.
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 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
