BV421 Rat Anti-Mouse IL-4
BV421 Rat Anti-Mouse IL-4
Flow cytometric analysis of IL-4 expressed in activated mouse splenocytes.  Splenocytes from C57BL/6 mice were enriched for CD4+ T cells by positive selection using Purified NA/LE Rat Anti-Mouse CD4 antibody-coated plates (GK1.5, Cat. No.553726;10 μg/ml) for 1 hr at 4°C. The CD4+ T cells were harvested and stimulated with plate-bound Purified NA/LE Hamster Anti-Mouse CD3e (145-2C11, Cat. No. 553057;10 μg/ml) and soluble Purified NA/LE Hamster Anti-Mouse CD28 (37.51, Cat. No. 553294; 2 μg/ml) antibody and Recombinant Mouse IL-2 (Cat. No. 550069; 10 ng/ml) and IL-4 (Cat. No. 550067; 50 ng/ml) for 2 days. The cells were expanded in IL-2 and IL-4 for 3 days and then washed and stimulated (4 hr)  with PMA (Sigma, Cat. No. P-8139; 5 ng/ml) and ionomycin (Sigma, Cat. No. P-8139; 500 ng) in the presence of BD GolgiPlug™ Protein Transport Inhibitor (Containing Brefeldin A) (Cat. No. 555029).  The activated cells were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655), permeabilized using the BD Perm/Wash™ Permeabilization Buffer (Cat. No. 554723) and then stained either with a BD Horizon™ BV421 Rat IgG1, κ Isotype Control (Cat. No. 562868, Left Panel) or with BD Horizon™ BV421 Rat Anti-Mouse IL-4 antibody (Cat. No. 562915, Right Panel). Two-color dot plots showing IL-4 (or Ig isotype control staining) versus autofluorescence were derived from gated events with the forward and light scattering characteristics of intact lymphocytes. Flow cytometry was performed using a BD LSR™ II Flow Cytometry System.

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 with BD Horizon BV421 under optimum conditions, and unconjugated antibody and free BD Horizon BV421 were removed.

11B11

Interleukin-4 (IL-4) is a pleiotropic cytokine that has many roles, such as inducing the differentiation of naïve helper T cells (Th0 cells) to Th2 cells, stimulating activated B-cell and T-cell proliferation, and promoting immunoglobulin class switching to IgG1 and IgE in mouse B-cells.  IL-4 is expressed by CD4 T-cells, mast cells, basophils and eosinophils.  IL-4 was previously known as B-Cell Differentiation Factor (BCDF) or B-cell Stimulatory Factor (BSF1).  The 11B11 monoclonal antibody specifically binds to mouse IL-4. The immunogen used to generate the 11B11 hybridoma was partially purified mouse IL-4 prepared from the supernatant of Phorbol 12-Myristate 13-Acetate (PMA)-stimulated EL-4 cells. The 11B11 antibody is reportedly a neutralizing antibody.

The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon™ BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon™ BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates.

BV421
The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
