Human CD56 is an adhesion molecule from the Ig superfamily which is restricted to NK cells in the immune system. It is believed that NK cells form a first line of defense against tumor cells and cells infected with bacteria and viruses.
Applications:
Suitable for use in ELISA and Flow Cytometry. Other applications not tested.
Recommended Dilution:
Flow Cytometry: 5x10e5 ficoll prepared human peripheral blood mononuclear cells were washed and pre-incubated 5 min with 20ul of 250ug/ml human IgG (to block non specific binding) after which they were incubated 45 min on ice with 80ul of anti-CD56 antibody at 10ug/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. A net 15% sub population of the cells stained positive with a mean shift of 0.91 log10 fluorescent units when compared to a Mouse IgG1 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.
