BB700 Rat Anti-Mouse CD19
BB700 Rat Anti-Mouse CD19
Two color flow cytometric analysis of CD19 expression on mouse splenocytes. Splenic leucocytes from a BALB/c mouse were preincubated with Purified Rat Anti-Mouse CD16/CD32 antibody (Mouse BD Fc Block™) (Cat. No. 553141/553142). The cells were then stained with BD Horizon™ BV421 Hamster Anti-Mouse CD3e antibody (Cat. No. 562600) and either BD Horizon™ BB700 Rat IgG2a, κ Isotype Control (Cat. No. 566413; Left Plot) or BD Horizon BB700 Rat Anti-Mouse CD19 antibody (Cat. No. 566411 /566412; Right Plot) at 0.125 μg/test. The two-color fluorescence contour plots showing the correlated expression patterns of CD19 (or Ig Isotype control staining) versus CD3e were derived from gated events with the forward and side light-scatter characteristic of viable splenic leucocytes. Flow cytometric analysis was performed using a BD LSRFortessa™ X-20 Cell Analyzer System. Data shown on this Technical Data Sheet are not lot specific.

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™ BB700 under optimum conditions, and unconjugated antibody and free BD Horizon BB700 were removed.

推奨アッセイ手順

 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 or 566349).

When setting up compensation, it is recommended to compare spillover values obtained from cells and BD™ CompBeads to ensure that beads will provide sufficiently accurate spillover values.

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

1D3

The 1D3 antibody reacts with CD19, a B lymphocyte-lineage differentiation antigen. CD19, a 95-kDa transmembrance glycoprotein, is a member of the immunoglobulin superfamily and is expressed throughout B-lymphocyte development from the pro-B cell through  the mature B-cell stages. Terminally differentiated plasma cells do not express CD19. On the surface of mature B cells, the CD19 molecule associates with CD21 (CR-2) and CD81 (TAPA-1), and this multimolecular complex synergizes with surface immunoglobulin to promote cellular activation. Studies with CD19-deficient mice have suggested that the level of CD19 expression affects the generation and maturation of B cells in the bone marrow and periphery. B-1 lineage B cells, also known as CD5+ B cells, are drastically reduced or absent in CD19-deficient mice. Increased levels of CD19 expression correlate with increased frequencies of peritonal and splenic B-1 cells and reduced numbers of conventional B lymphocytes in the periphery. CD19 participates in B-lymphocyte development, B-cell activation, maturation of memory B cells and regulation of tolerance. CD19 has also been detected on peritoneal mast cells, co-localized with CD21/CD35, and it is proposed to play a role in complement-mediated mast-cell activation.

  

The antibody was conjugated to BD Horizon BB700, which is part of the BD Horizon Brilliant™ Blue family of dyes. It is a polymer-based tandem dye developed exclusively by BD Biosciences. With an excitation max of 485 nm and an emission max of 693 nm, BD Horizon BB700 can be excited by the 488 nm laser and detected in a standard PerCP-Cy™5.5 set (eg, 695/40-nm filter). This dye provides a much brighter alternative to PerCP-Cy5.5 with less cross laser excitation off the 405 nm and 355 nm lasers.

BB700
The BD Horizon Brilliant™ Blue 700 (BB700) Dye is part of the BD Horizon Brilliant™ Blue family of dyes. This tandem fluorochrome is comprised of a polymer-technology dye donor with an excitation maximum (Ex Max) of 476-nm and an acceptor dye with an emission maximum (Em Max) at 695-nm. Driven by BD innovation, BB700 is designed to be excited by the blue laser (488-nm) and detected using an optical filter centered near 695-nm (e.g., a 695/20-nm bandpass filter). The donor dye can be excited by the Violet (405 nm) laser and the acceptor dye can be excited by the red (627–640 nm) laser resulting in cross-laser excitation and fluorescence spillover. BB700 Reagents are significantly brighter than equivalent PerCP or PerCP-Cy5.5 reagents and are less sensitive to photobleaching. In addition, BB700 shows much less excitation by the violet (407-nm) laser resulting in less spillover. BB700 has minimal yellow green (562-nm) excitation and is ideal for instruments with both blue (488-nm) and yellow green (562-nm) lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
