Regulatory Status Legend
The pre-B cell receptor (pre-BCR) expressed during the early stages of B lymphocyte development is a heterodimer of immunoglobulin heavy chain (IgH) with surrogate light chain, which is an Ig-light-chain-like molecule composed of the non-covalently linked CD179b (λ5) and CD179a (VpreB) proteins. The pre-BCR is believed to control IgH repertoire selection and proliferation of differentiating B lymphocytes. The LM34 antibody reacts with λ5 and surrogate light chain, but not VpreB alone, in transfected X63-Ag8.653 cells. It detects surrogate light chain on pro-B and pre-B cell lines, in the presence or absence of IgH, but not on IgM-positive B lymphocytes. It also detects surrogate light chain or λ5 on the surface and in the cytoplasm of pro-B or pre-B cells from the bone marrow of normal or RAG2-deficient mice. It has been noted that the (CD45R/B220) cell-surface expression of surrogate light chain is upregulated after a one-hour incubation of bone-marrow leukocytes in tissue culture medium at 37°C. At the earliest stages of B lymphopoiesis, before IgH is available, the surrogate light chain associates with a complex of glycoproteins, including a nonclassical cadherin, which could be involved in selective adhesion events during B-lymphocyte development. After immunization, cell-surface λ5 is detected on a subset of splenic Ig light chain-positive germinal-center B lymphocytes.
The antibody was conjugated to BD Horizon™ BUV805 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348 nm and an acceptor dye with an Em Max at 805 nm. BD Horizon Brilliant BUV805 can be excited by the ultraviolet laser (355 nm) and detected with a 820/60 filter and a 770LP.
BUV805 is a tandem fluorochrome that combines BD Horizon BUV395 and an acceptor dye with an Em Max at 805 nm. BUV805 has been exclusively developed by BD Biosciences for instruments equipped with a 355-nm UV laser.

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 BUV805 under optimal conditions that minimize unconjugated dye and antibody.
- This antibody was developed for use in flow cytometry.
- 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.
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) 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).
