GlycoErase™ SIGLEC1 Knockout HEK293 Cell Line (CAT#: GLJF-0825-JF840)

Description	GlycoErase™ SIGLEC1 knockout HEK293 cell line is a human embryonic kidney (HEK293) cell line in which SIGLEC1 expression has been eliminated. SIGLEC1 is a sialic acid-dependent adhesion receptor involved in immune regulation and pathogen entry, including viral enhancement. The knockout of SIGLEC1 in the HEK293 background provides a versatile model for studying glycan-mediated interactions, viral infection mechanisms, and immune modulation, and supports applications in protein expression research, antibody validation, and host-pathogen studies.

Summary	This gene encodes a protein from the immunoglobulin superfamily, which functions as a lectin-like adhesion molecule, binding glycoconjugate ligands on cell surfaces in a sialic acid-dependent manner. It is a type I transmembrane protein expressed by a subpopulation of macrophages, playing a critical role in cell-cell interactions. The protein is involved in a variety of human diseases and infections, and it has been shown to enhance SARS-CoV-2 infection.
