Scientific Data Images for CD44 Antibody

Knockout Validated: CD44 Antibody [NBP1-31488]

Knockout Validated: CD44 Antibody [NBP1-31488]

Knockout Validated: CD44 Antibody [NBP1-31488] - Wild-type (WT) and CD44 knockout (KO) HeLa cell extracts (30 ug) were separated by 7.5% SDS-PAGE, and the membrane was blotted with CD44 antibody.
Western Blot: CD44 Antibody [NBP1-31488]

Western Blot: CD44 Antibody [NBP1-31488]

Western Blot: CD44 Antibody [NBP1-31488] - Various whole cell extracts (30 ug) were separated by 7.5% SDS-PAGE, and the membrane was blotted with CD44 antibody diluted at 1:7000. Multiple bands were observed 130-180 kDa. It is possibly due to alternative splicing.
Western Blot: CD44 Antibody [NBP1-31488]

Western Blot: CD44 Antibody [NBP1-31488]

Western Blot: CD44 Antibody [NBP1-31488] - Untreated (-) and treated (+) MDA-MB-231 whole cell extracts (30 ug) were separated by 7.5% SDS-PAGE, and the membrane was blotted with CD44 antibody. The observed M.W. is different from the predicted size. It is possibly due to post-translational modifications.

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
