Description
The MEM-166 monoclonal antibody specifically binds to CD177 which is also known as NB1 (Neutrophil-specific antigen), HNA-2a (Human neutrophil alloantigen 2a), and PRV1 (Polycythemia rubra vera 1). CD177 is a glycophosphatidylinositol (GPI)-anchored plasma membrane glycoprotein (56-64 kDa). CD177 is expressed on subpopulations of neutrophils, neutrophillic metamyelocytes and myelocytes from 89 to 97% of healthy individuals. It is also expressed on secondary granules. Its expression is upregulated on granulocytes stimulated with the chemotactic peptide f-met-leu-phe (fMLP). Although the function of CD177 has not been fully established, some reports suggest its possible role as receptor molecule involved in leucocyte migration.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.
1. Researchers should determine the optimal concentration of this reagent for their individual applications.
2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
3. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
4. An isotype control should be used at the same concentration as the antibody of interest.
5. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

8. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
9. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
10. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.
