Description

The BTLA antibody reacts with mouse BTLA, B and T lymphocyte attenuator from both BALB/c and C57Bl/6 strains. BTLA is expressed by peripheral lymphocytes, splenic macrophages, developing B cells in the bone marrow and developing T cells in thymus and mature, but not immature bone marrow-derived dendritic cells. BTLA is implicated as a negative regulator of the activation and/or function of various hemopoietic cell types. It is reported that BTLA binds to B7-H4, but further studies are needed to confirm this interaction.

Note: The anti-mouse BTLA monoclonal antibody 6F7 is reported to stain CD4+ and CD8+ single-positive (SP) thymocytes (Hurchla et al). However, other anti-mouse BTLA clones generated simultaneously with 6F7 (8F4, 3F9.D12, 6G3 and 6H6) do not stain SP thymocytes . It is not understood why there is a discrepancy in thymocyte staining. However, in staining of splenocytes and bone marrow cells, clones 8F4, 3F9.D12, 6G3 and 6H6 stain similar populations to 6F7.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This 8F4 antibody has been reported for use in flow cytometric analysis.

Applications Tested

This 8F4 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.25 μg per million cells in a 100 μl total staining volume. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
