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 that minimize unconjugated dye and antibody.

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 CompBead to ensure that BD CompBeads 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).

Note:  When using high concentrations of antibody, background binding of this dye to erythroid cell subsets (mature erythrocytes and precursors) has been observed.  For researchers studying these cell populations, or in cases where light scatter gating does not adequately exclude these cells from the analysis, this background may be an important factor to consider when selecting reagents for panel(s).

Product Notices

  1. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
  2. Researchers should determine the optimal concentration of this reagent for their individual applications.
  3. An isotype control should be used at the same concentration as the antibody of interest.
  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.

The HMFG2 (Milk Fat Globule 2) monoclonal antibody, formerly known as clone 3.14.A3, specifically binds to Mucin-1 (MUC1) which is also known as CD227, Episialin, Breast carcinoma-associated antigen DF3, Cancer antigen 15-3, H23 antigen, Peanut reactive urinary protein (PUM), Polymorphic epithelial mucin (PEM), or Epithelial membrane antigen (EMA). MUC1 (CD227) is a heterodimeric cell surface glycoprotein that belongs to the epithelial mucin family. As a result of proteolytic cleavage, MUC1 (CD227) is comprised of a large, extracellular N-terminal alpha subunit that contains a domain of 20 amino-acid tandem repeats and functions in cellular adhesion. The smaller transmembrane C-terminal beta subunit contains a cytoplasmic domain that is involved in cell signaling. MUC1 (CD227) is variably expressed on the surfaces of normal and malignant glandular and ductal epithelial cells, myeloma cells, and some hematopoietic cell lineages including subsets of T cells, B cells, monocytes and dendritic cells. Soluble forms of MUC1 (CD227) may arise by shedding from the cell surface or by secretion of forms derived from alternative RNA splicing. MUC1 (CD227) plays roles in the provision of protective barrier function, the regulation of cellular adhesion and migration, and the transduction of multiple signal pathways. The HMFG2 antibody recognizes epitopes within the tandem repeat domain of MUC1 (CD227).

The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP.  Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).

The BD Horizon Brilliant™ Ultraviolet 615 (BUV615) Dye is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This tandem fluorochrome is comprised of a BUV395 donor with an excitation maximum (Ex Max) of 350-nm and an acceptor dye with an emission maximum (Em Max) at 615-nm. BUV615, driven by BD innovation, is designed to be excited by the ultraviolet laser (355 nm) and detected using an optical filter centered near 615-nm (e.g, 610/20 bandpass filter). The acceptor dye can be excited by the Blue (488-nm) and yellow-green (561-nm) lasers resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
