GlycoErase™ SIGLEC5 Knockout CHO-K1 Cell Line (CAT#: GLJF-0825-JF887)

Description	GlycoErase™ SIGLEC5 knockout CHO-K1 cell line is a CHO-K1 model with SIGLEC5 expression removed. SIGLEC5 belongs to the CD33-related Siglec subset and acts as a sialic acid-binding lectin that suppresses the activation of monocytes, macrophages, and neutrophils, and also mediates immune evasion by group B Streptococcus (GBS). This knockout CHO-K1 system supports research into innate immune regulation, bacterial interactions, and immune escape, and serves as a platform for therapeutic antibody development and functional immunology studies.

Target	SIGLEC5
Full Name	Sialic Acid Binding Ig Like Lectin 5
Alternative Name	CD170, OBBP2, CD33L2, OB-BP2, SIGLEC-5, Sialic Acid Binding Ig Like Lectin
Location	19q13.41
Gene ID	8778
Summary	This gene encodes a member of the sialic acid-binding immunoglobulin-like lectin (Siglec) family. These cell surface lectins have structural motifs in their immunoglobulin-like domains and sialic acid recognition sites in the first Ig V-set domain. The encoded protein, part of the CD33-related Siglec subgroup, inhibits activation in monocytes, macrophages, and neutrophils. It also plays a role in immune evasion by Group B Streptococcus (GBS).
