推奨アッセイ手順
Put all BD® AbSeq Reagents to be pooled into a Latch Rack for 500 µL Tubes (Thermo Fisher Scientific Cat. No. 4900). Arrange the tubes so that they can be easily uncapped and re-capped with an 8-Channel Screw Cap Tube Capper (Thermo Fisher Scientific Cat. No. 4105MAT) and the reagents aliquoted with a multi-channel pipette.
BD® AbSeq tubes should be centrifuged for ≥ 30 seconds at 400 × g to ensure removal of any content in the cap/tube threads prior to the first opening.

- This reagent has been pre-diluted for use at the recommended volume per test. Typical use is 2 µl for 1 × 10^6 cells in a 200-µl staining reaction.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- 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 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.

コンパニオン製品
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 Lambda 5 (λ5) and VpreB proteins. The pre-BCR is believed to control IgH repertoire selection and proliferation of differentiating B lymphocytes. The SL156 antibody reacts with a conformational epitope of the pre-BCR in transfected X63-Ag8.653 cells but not with surrogate light chain, λ5, or VpreB in the absence of IgH. It detects pre-BCR on pre-B cell lines, but not on pro-B cell lines or IgM-positive splenocytes. It also detects pre-BCR on the surface of pre-B cells, but not on Ig light chain (IgL)-positive B lymphocytes, from the bone marrow of normal mice. It has been noted that the cell-surface expression of pre-BCR is upregulated after a one-hour incubation of bone-marrow leukocytes in tissue culture medium at 37°C. After immunization, cell-surface pre-BCR is detected on a subset of splenic IgL+ germinal-center B lymphocytes.
