Alexa Fluor™ 488-Labeled Human Siglec-2 / CD22 Protein, His TagStar Staining

ACROBiosystems

DESCRIPTION

Alexa Fluor 488-Labeled Human Siglec-2, His Tag (SI2-HA2H7) is produced via conjugation of AF488 to Human Siglec-2, His Tag with a new generation site-specific technology under Star Staining labeling platform. Human Siglec-2, His Tag is expressed from human 293 cells (HEK293). It contains AA Asp 20 - Arg 687 (Accession # P20273-1).

  • Background: B-cell receptor CD22 is also known as Sialic acid-binding Ig-like lectin 2 (Siglec-2), B-lymphocyte cell adhesion molecule (BL-CAM), T-cell surface antigen Leu-14, which belongs to the immunoglobulin superfamily and SIGLEC (sialic acid binding Ig-like lectin) family. CD22 mediates B-cell B-cell interactions, and may be involved in the localization of B-cells in lymphoid tissues. Siglec-2 / CD22 binds sialylated glycoproteins, one of which is CD45. Siglec2 / CD22 plays a role in positive regulation through interaction with Src family tyrosine kinases and may also act as an inhibitory receptor by recruiting cytoplasmic phosphatases via their SH2 domains that block signal transduction through dephosphorylation of signaling molecules.
