Flow Cytometry Product Notes:
Test Sizes: To accommodate multicolor flow cytometry, eBioscience is in the process of reducing test size volumes from 20 µl to 5 µl. Please check your antibody vial for the recommended test size.
Fluorochrome Replacements: eBioscience is in the process of replacing all Pacific Blue® and APC-Alexa Fluor® 750 conjugated products with eFluor™ 450 and APC-eFluor™ 780 conjugated products, respectively. |

Description
The BTLA monoclonal antibody reacts with human B and T lymphocyte attenuator (BTLA). BTLA is expressed by peripheral lymphocytes, splenic macrophages, developing B cells in the bone marrow and developing T cells in the 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.
Applications Reported
For research use only, not for diagnostic or therapeutic use. This MIH26 antibody has been reported for use in flow cytometric analysis.
Applications Tested
This MIH26 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood. Please refer to the antibody vial for the recommended test volume to use for one million cells in a 100 μl total staining volume.
Note: Due to poor stability, the PE format of clone MIH26 is being discontinued, and the current lot is only guaranteed until October 1, 2009. Please contact tech@ebioscience.com for more information.
