  • Synonym
    CD93,CDw93,C1QR1,MXRA4,C1qR,C1qR(P),C1qRP,ECSM3
  • Source
    Human C1q R1, His Tag (C11-H5228) is expressed from human 293 cells (HEK293). It contains AA Thr 22 - Lys 580 (Accession # AAH28075).
    Predicted N-terminus: Thr 22
  • Molecular Characterization
    Online(Thr 22 - Lys 580) AAH28075

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 59.2 kDa. The protein migrates as 70-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

  • Background
    CD antigen CD93 is also known as Complement component C1q receptor (C1QR1). which belongs to the Group XIV C-Type lectin family, a group containing two other members, endosialin (CD248) and thrombomodulin. CD93 contains one C-type lectin domain and five EGF-like domains. CD93 is highly expressed in endothelial cells, platelets, cells of myeloid origin, such as monocytes and neutrophils. CD93 is receptor for C1q, mannose-binding lectin (MBL2) and pulmonary surfactant protein A (SPA). CD93 may mediate the enhancement of phagocytosis in monocytes and macrophages upon interaction with soluble defense collagens and may play a role in intercellular adhesion.
