Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.

Recommended Assay Procedures

For optimal staining of peripheral lymphoid tissue, we recommend the use of Mouse BD Fc Block™ (anti-mouse CD16/CD32 mAb 2.4G2, Cat. No. 553141/553142), an isotype-specific second-step antibody, and amplification of the staining signal by use of a biotinylated second-step antibody (such as biotinylated anti-mouse IgG2b mAb R12-3, Cat. No. 553393) followed by a "bright" third-step reagent, such as Streptavidin-PE (Cat. No. 554061) or Streptavidin-APC (Cat. No. 554067).

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. 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.
  4. Sodium azide is a reversible inhibitor of oxidative metabolism; therefore, antibody preparations containing this preservative agent must not be used in cell cultures nor injected into animals. Sodium azide may be removed by washing stained cells or plate-bound antibody or dialyzing soluble antibody in sodium azide-free buffer. Since endotoxin may also affect the results of functional studies, we recommend the NA/LE (No Azide/Low Endotoxin) antibody format, if available, for in vitro and in vivo use.

The BP-3 antibody reacts with CD157, also known as the BP-3 alloantigen or Bone marrow STromal cell antigen-1 (BST-1), found in a variety of common laboratory strains of mice (AKR, BALB/c, CBA/N, C3H/HeJ, C57BL/6, DBA/2, NZB, C.B-17, SJL and Swiss, but not A/J). CD157 is a differentially glycosylated GPI-linked cell-surface glycoprotein with a core protein of 32 kDa and differing patterns of glycosylation in different types of cells. It is a member, along with CD38, of a family of genetically-related ectoenzymes. The BP-3 alloantigen is expressed on the B lineage from the earliest detectable progenitors to circulating immature B lymphocytes, on immature thymocytes up to the   expression of the T-cell receptor, on circulating neutrophils, peritoneal macrophages, on subpopulations of stromal cells in peripheral lymphoid organs (but not in bone marrow or thymus), on intestinal epithelial cells, and in the  lumen of kidney-collecting tubules. The distribution of CD157 antigen on leukocytes and stromal cells of lymphoid organs suggests that it may be involved in leukocyte-stroma interactions which support the development, migration, and/or responses of leukocyte populations.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
