BD Pharmingen™ Alexa Fluor™ 488 Rat Anti-Mouse Ly-49A
Clone YE1/48.10.6 (also known as YE1/48)
(RUO)Multicolor flow cytometric analysis of Ly-49A expression on Mouse splenic leukocytes. C57BL/6 Mouse splenocytes were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) [Cat. No. 553141/553142]. The cells were then stained with BD Horizon™ BV421 Rat Anti-Mouse CD49b antibody (Cat. No. 563063) and with either Alexa Fluor™ 488 Rat IgG2b, κ Isotype Control (Cat. No. 557726; Left Plot) or Alexa Fluor™ 488 Rat Anti-Mouse Ly-49A antibody (Cat. No. 570081/570162; Right Plot) at 0.25 μg/test. BD Via-Probe™ Cell Viability 7-AAD Solution (Cat. No. 555815/555816) was added to cells right before analysis. The bivariate pseudocolor density plot showing the correlated expression of Ly-49A (or Ig Isotype control staining) versus CD49b was derived from gated events with the forward and side light-scatter characteristics of viable (7-AAD-negative) splenic leukocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ Software. Data shown on this Technical Data Sheet are not lot specific.

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.
Product Notices
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- An isotype control should be used at the same concentration as the antibody of interest.
- Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
- 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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Please refer to http://regdocs.bd.com to access safety data sheets (SDS).

The YE1/48.10.6 monoclonal antibody specifically recognizes Lymphocyte antigen 49a (Ly-49A). Ly-49A is a single-pass type-II transmembrane that is encoded by Klra1 (Killer cell lectin-like receptor, subfamily A member 1) which belongs to the C-type lectin superfamily. Ly-49A is comprised of an extracellular carbohydrate-recognition domain (CRD) that can bind strongly to H-2D MHC class I alloantigens expressed on target cells including H-2D[d], H-2D[k], and H-2D[p]. The extracellular domain is followed by a transmembrane region and a cytoplasmic domain with an immunoreceptor tyrosine-based inhibitory motif (ITIM). Ly-49A is expressed as a disulfide-linked homodimer on a subset of NK and NK-T cells. MHC Class I ligand-bound Ly-49A can negatively regulate NK-cell cytolytic activity via tyrosine phosphorylation of its ITIM.
