General description

Virtually all lymphoid and myeloid cells in bone marrow are reactive with the anti-VLA-4 antibody. VLA-4 is absent or minimally detectable on stromal cells. Myeloid cells maintained in Dexter-type long-term cultures of murine bone marrow are positive, as are lymphoid cells from Whitlock-White cultures.

Specificity

Clone PS/2 recognises the murine alpha4 chain of the VLA-4 integrin heterodimer, 150 kDa. The antibody also reacts with human VLA-4.
Reactivity with other species has not been confirmed.

Application

Anti-Integrin α4 Antibody, clone PS/2 detects level of Integrin α4 & has been published & validated for use in FC, IF, IP, IH.
Flow cytometry: 2 μg per 106 cells

Immunohistochemistry on frozen tissue sections

Immunoprecipitation

Cell adhesion assays

Optimal working dilutions must be determined by the end user.

    Myeloid cells play key roles in cancer immune suppression and tumor progression. In response to tumor derived factors, circulating monocytes and granulocytes extravasate into the tumor parenchyma where they stimulate angiogenesis, immune suppression and tumor progression.
