RB545 Mouse Anti-Human CD42a
RB545 Mouse Anti-Human CD42a
Flow cytometric analysis of CD42a expression on Human resting platelets.  Platelets were isolated from fresh Human whole blood and fixed with 2% formaldehyde. After washing, the fixed platelets were stained with either BD Horizon™ RB545 Mouse IgG1, κ Isotype Control (Cat. No. 569284; dashed line histogram) or BD Horizon™ RB545 Mouse Anti-Human CD42a (Cat. No. 569733/569761; solid line histogram). The fluorescence histogram showing CD42a expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of intact platelets. Samples were acquired on the BD FACSymphony™ A5 SE Cell Analyzer and spectrally unmixed using FlowJo™ v10.8 software.

Preparation And Storage

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 and unreacted dye was removed.

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

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. 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).
  3. An isotype control should be used at the same concentration as the antibody of interest.
  4. 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.
  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.
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  7. 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.

ALMA.16

The ALMA.16 monoclonal antibody specifically recognizes CD42a. CD42a is a 17-22 kDa type I transmembrane glycoprotein that is also known as Platelet glycoprotein IX (GPIX), or Glycoprotein 9 (GP9). CD42a forms a noncovalently linked complex (GPIb/GPIX/GPV) with CD42b, CD42c and CD42d that may serve as a receptor for von Willebrand factor. It is expressed on platelets and megakaryocytes and is absent on the platelets of patients with Bernadr-Soulier Syndrome (BSS). Although the CD42a function is not fully understood, GPIX glycoprotein is important for the assembly and membrane expression of the CD42 complex and for the maintenance of the functional conformation of CD42b (GPIb).

RB545
The BD Horizon RealBlue™ 545 (RB545) fluorochrome is part of the BD family of blue (488-nm) laser dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 496-nm and an emission maximum (Em Max) at 545-nm. Driven by BD innovation, RB545 can be used on spectral cytometers and is designed to be excited by the blue (488-nm) laser with minimal excitation by the 561-nm yellow-green laser. RB545 has minimal spillover into yellow-green detectors and a brightness level similar to FITC.  Given its unique emission max, on a spectral instrument RB545 can be used simultaneously with FITC and PE to provide an additional color off of the blue laser. Please ensure that your instrument configuration (lasers and optical filters) is appropriate for this dye.
