Multicolor flow cytometric analysis of CD57 expression on human peripheral blood lymphocytes. Human whole blood was stained with APC Mouse Anti-Human CD3 antibody (Cat. No. 555335/561810/561811) and with either BD Horizon™ BV605 Mouse IgM, κ Isotype Control (Cat. No. 563517; Left Plot) or BD Horizon™ BV605 Mouse Anti-Human CD57 antibody (Cat. No. 567205; Right Plot). The erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). The bivariate pseudocolor density plot showing the correlated expression of CD57 (or Ig Isotype control staining) versus CD3 was derived from events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometry and data analysis were performed using a BD FACSymphony™ A5 SE Flow Cytometer System and FlowJo™ software.

Preparation And Storage
Recommended Assay Procedures
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.
For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).
Product Notices
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
- 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.
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- An isotype control should be used at the same concentration as the antibody of interest.
- CF™ is a trademark of Biotium, Inc.
- Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from BD Horizon™ BV421 may be observed. Therefore, we recommend that individual compensation controls be performed for every BD Horizon™ BV605 conjugate.

The NK-1 monoclonal antibody specifically reacts with a 110 kDa carbohydrate antigen associated with myelin-associated glycoprotein expressed on 7-35% of normal peripheral blood lymphocytes including a subset of natural killer cells, a subset of CD8-positive peripheral blood T cells, and on some neural tissues. CD57 is not expressed on granulocytes, platelets, red blood cells or thymocytes. The function of CD57 is still unclear, however, its expression on T-cell subets occurs in late immune responses.
