BB515 Mouse Anti-Human NKp44 (CD336)
BB515 Mouse Anti-Human NKp44 (CD336)

Multicolor flow cytometric analysis of NKp44 (CD336) expression by IL-2-activated large granular lymphocytes. Human peripheral blood mononuclear cells were cultured (7 days, 37°C) with recombinant human IL-2 protein (Cat. No. 554603). The IL-2-activated cells were then stained with PE Mouse Anti-Human CD3 (Cat. No. 555333/561808/561809) and APC Mouse Anti-Human CD56 (Cat. No. 555518) antibodies, and either BD Horizon™ BB515 Mouse IgG1, κ Isotype Control (Cat. No. 564416; dashed line histogram) or BD Horizon BB515 Mouse Anti-Human NKp44 (CD336) antibody (Cat. No. 565099/566025; solid line histogram). The fluorescence histogram showing NKp44 (CD336) expression (or Ig Isotype control staining) was derived from CD3- CD56+ gated events with the forward and side light-scatter characteristics of large granular lymphocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

調製と保管

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 with BD Horizon™ BB515 under optimum conditions and unconjugated antibody was removed.

推奨アッセイ手順

BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation).  When fluorochrome conjugated antibodies are bound to 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 CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions.  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).

For optimal results, it is recommended to perform 2 washes after staining with antibodies. Cells may be prepared, stained with antibodies and washed twice with wash buffer per established protocols for immunofluorescence staining, prior to acquisition on a flow cytometer. Performing fewer than the recommended wash steps may lead to increased spread of the negative population.

  1. 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).
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. 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.
  4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

p44-8

The p44-8 monoclonal antibody specifically binds to the natural killer (NK) cell receptor, NKp44, which is also known as CD336, Natural cytotoxicity triggering receptor 2 (NCR2), or Lymphocyte antigen 95 homolog (Ly95). NKp44 is a ~44 kDa type I transmembrane protein that belongs to the natural cytotoxicity receptor (NCR) family within the immunoglobulin superfamily. NKp44 is expressed by activated NK cells. NKp44 serves as an activating receptor that can enhance NK cell mediated lysis of target cells including tumor cells and virus-infected cells. Killer activating receptor associated protein (KARAP), which is also known as DAP12, is an intracellular adaptor protein that can associate with the intracellular region of NKp44. DAP12 can then function to help transmit activating signals through its immunoreceptor tyrosine-based activation motif (ITAM).

The antibody was conjugated to BD Horizon BB515 which is part of the BD Horizon Brilliant™ Blue family of dyes. With an Ex Max near 490 nm and an Em Max near 515 nm, BD Horizon BB515 can be excited by the blue laser (488 nm) laser and detected with a 530/30 nm filter. This dye has been exclusively developed by BD Biosciences and is up to seven times brighter than FITC with less spillover into the PE channel. Due to similar excitation and emission properties, BB515, FITC, and Alexa Fluor® 488 cannot be used simultaneously. It is not recommended to use BB515 in cocktails that include Streptavidin conjugates as it may cause high background.

BB515
The BD Horizon Brilliant™ Blue 515 (BB515) dye is part of the BD Horizon Brilliant™ Blue family of dyes. This dye is a polymer fluorochrome with an excitation maximum (Ex Max) at 490-nm and an emission maximum (Em Max) of 515-nm. Driven by BD innovation, BB515 is designed to be excited by the blue laser (488-nm) and detected using an optical filter centered near 520-nm (e.g., 530/30-nm). BB515 reagents are significantly brighter than equivalent FITC or Alexa Fluor™ 488 reagents with less spillover into the PE detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
