  • 追加情報Is unsuitable for Flow Cyt or ICC/IF.
  • ターゲット情報

    • 機能This protein may be involved in the regulation of B-cell activation and proliferation.
    • 組織特異性Expressed on B-cells.
    • 関連疾患Defects in MS4A1 are the cause of immunodeficiency common variable type 5 (CVID5) [MIM:613495]; also called antibody deficiency due to CD20 defect. CVID5 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B cells is usually in the normal range, but can be low.
    • 配列類似性Belongs to the MS4A family.
    • 翻訳後修飾Phosphorylated. Might be functionally regulated by protein kinase(s).

    • Unpurified ab78237 showing positive staining in normal tonsil tissue.

    • Immunohistochemical staining of paraffin embedded B cell lymphoma with purified ab78237 at a working dilution of 1/50. The secondary antibody used is ab97051, a goat anti-rabbit IgG (H&L) at a dilution of 1/500. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.
