Unconjugated Human CD47 Protein, His,Avitag™

  • シノニム
    CD47,MER6,IAP,OA3
  • ソース
    Unconjugated Human CD47, His,Avitag (CD7-HA2E9) is expressed from human 293 cells (HEK293). It contains AA Gln 19 - Pro 139 (Accession # Q08722-3).
    Predicted N-terminus: Gln 19
  • 分子特性
    Online(Gln 19 - Pro 139) Q08722-3

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

    The protein has a calculated MW of 16.9 kDa. The protein migrates as 33-44 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • 用途
    CD7-HA2E9 is the unconjugated version of CD7-H82E9 (Biotinylated Human CD47, His,Avitag). It can be utilized for assay development or customized biotinylation according to the experimental designs.
  • エンドトキシン
    Less than 1.0 EU per μg by the LAL method.
  • 純度

    >95% as determined by SDS-PAGE.

  • 成分

    Lyophilized from 0.22 μm filtered solution in 10 mM Bicine, pH8.3. Normally trehalose is added as protectant before lyophilization.

    Appropriate buffer for directly in vitro enzymatical labeling, please contact us for customized formulation.

  • 再構成

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • 保存

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

  • バックグラウンド
    Leukocyte surface antigen CD47 is also known as Antigenic surface determinant protein OA3, Integrin-associated protein (IAP) and Protein MER6. CD47 contains 1 Ig-like V-type (immunoglobulin-like) domain. CD47 is very broadly distributed on normal adult tissues. CD47 has a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins and plays an important role in memory formation and synaptic plasticity in the hippocampus by similarity. CD47 is the receptor for SIRPA, binding to which prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. CD47 Interaction with SIRPG mediates cell-cell adhesion, enhances superantigen-dependent T-cell-mediated proliferation and costimulates T-cell activation.
