GlycoErase™ SIGLEC5 Knockout CHO-K1 Cell Line

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.

Upon receipt, this product must be immediately transferred from dry ice to liquid nitrogen (-150°C to -190°C) and stored in a liquid nitrogen tank. Cell viability is critically dependent on proper handling. We cannot guarantee viability if these instructions are not strictly adhered to.

This product is provided for research only, not suitable for human or animal use. Due to the inherent limitations of infectious agent testing, investigators must exercise extreme caution when handling cells provided by Creative Biolabs, treating all cells as potentially biohazardous.

SIGLEC5

Sialic Acid Binding Ig Like Lectin 5

CD170, OBBP2, CD33L2, OB-BP2, SIGLEC-5, Sialic Acid Binding Ig Like Lectin

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).
