Alexa Fluor™ 647 Mouse Anti-Human CD40L (CD154)
Alexa Fluor™ 647 Mouse Anti-Human CD40L (CD154)
Flow cytometric analysis of CD40L (CD154) expression on stimulated human peripheral blood lymphocytes. Human peripheral blood mononuclear cells (PBMCs) were stimulated for 4 hours with 20 ng/mL Phorbol 12-Myristate 13-Acetate (PMA; Sigma-Aldrich Cat. No. P-8139) and 250 ng/mL Calcium Ionophore A23187 (Sigma-Aldrich Cat. No. C-9275). The cells were then preincubated with Human BD Fc Block™ (Cat. No. 564219/564220) and stained with either Alexa Fluor™ 647 Mouse IgG1, κ Isotype Control (Cat. No. 565571; dotted line histogram) or Alexa Fluor™ 647 Mouse Anti-Human CD40L (CD154) antibody (Cat. No. 568172/568174; solid line histogram). The fluorescence histogram showing CD40L (CD154) expression (or Ig Isotype control staining) was derived from gated events with the forward and side light-scatter characteristics of viable lymphocytes. Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software.

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.

推荐的实验流程

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 cell and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

商品通知

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  4. 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.
  5. 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).
  6. An isotype control should be used at the same concentration as the antibody of interest.
  7. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

24-31

The 24-31 monoclonal antibody specifically binds to CD40 Ligand (CD40L) which is also known as CD154, gp39, T-B cell-activating molecule (T-BAM), Tumor necrosis factor ligand superfamily member 5 (TNFSF5), and TNF-related activation protein (TRAP). CD40L (CD154) is an ~39 kDa type II membrane glycoprotein that is encoded by CD40LG. It is expressed on a variety of cell types including activated CD4+ T cells and some CD8+ T cells, NK cells, mast cells and basophils. CD40L (CD154) serves as a ligand for CD40 that is expressed on B cells, macrophages, and dendritic cells.  The expression of CD40L (CD154) by activated T-helper cells costimulates B-cell activation and proliferation through binding to CD40 expressed on B cells. In response to T-dependent antigens, the CD40L (CD154) and CD40 interaction is required for B-lymphocyte differentiation, including immunoglobulin production and isotype switching and memory B cell generation. The 24-31 antibody can reportedly block T cell-B cell interaction and inhibit the subsequent proliferation, differentiation, and memory formation of B cells. It has been reported that patients with X-linked hyper-IgM syndrome have defective expression of functional CD40L (CD154) due to mutations in the CD40LG gene.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor™ 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 670-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
