Product Specifications

Immunogen

This antibody was produced by immunizing a Fischer rat with human tonsil lymphocytes (10^7cells intraperitoneally in Freund's complete adjuvant). A boost was given 2 weeks later (intravascularly in saline).

Specificity

This antibody is specific for CD44 (gp90 epitope cluster I), which is selectively expressed on normal or transformed lymphoid cells that are able to recognize and bind to high endothelial venules (specialized vessels that mediate lymphocyte exit from the blood into lymphoid organs). Although this antibody was raised against human CD44, it cross-reacts with murine, rat, rabbit, primate, sheep, bovine and goat CD44.

Flow Cytometry: CD44 Antibody (Hermes-1) - Chimeric [NBP2-81088] - Flow-cytometry using anti-CD44 antibody (Hermes-1) [NBP2-81088]. Human activated T lymphocytes were stained with an isotype control (NBP2-52638, panel A) or the rabbit-chimeric version of Hermes-1 (NBP2-81088, panel B) at a concentration of 1 ug/ml for 30 mins at RT. After washing, bound antibody was detected using a AF488 conjugated donkey anti-rabbit antibody and cells analysed on a FACSCanto flow-cytometer.

Application Notes
This chimeric rabbit antibody was made using the variable domain sequences of the original Rat IgG2a format, for improved compatibility with existing reagents, assays and techniques. This antibody binds CD44, so can be used to label CD44+ cells in flow cytometry analysis. As CD44 molecules are used to bind to high endothelial venules (HEV) at the site of lymphoctye entry to lymphoid organs, this antibody can be used to specifically stain HEV-binding cell lines (Jalkanen, 1986). In addition, this antibody blocks the adhesion of the haematopoietic progenitor cell line KG1 to hyaluronic acid (Bendall, 2003), but does not block lymphocyte binding to HEV (Picker, 1989). 7H9D6 partially blocks the binding of this antibody.

Background: CD44

CD44 represents a family of type I transmembrane glycoproteins expressed on many cell types such as B cells, monocytes, macrophages, and variable subsets of thymocytes and peripheral T cells. CD44 primarily functions as an adhesion molecule. It has been implicated in various processes, such as hematopoiesis, lymphocyte homing, leukocyte activation, tumor metastasis and development. The KM201 monoclonal antibody reacts with an epitope very close to the hyaluronate binding domain on the CD44 molecule. KM201 can inhibit hyaluronate-dependent cell aggregation, prevent lympho-hemopoiesis in both Dexter and Whitlock-Witte Cultures, prevent the earliest intrathymic precursors from homing to the thymus, and costimulate the activation of freshly purified splenic CD4+ T cells.1-6
