Human Dectin-1 neutralizing and detection antibody - Monoclonal Mouse IgG1

Neutralizing and detection antibody against hDectin-1
Neutralizing and detection antibody against hDectin-1

Anti-hDectin-1-IgG (clone 22H8) is a monoclonal mouse IgG1 antibody against human Dectin-1 (hDectin-1). This antibody was screened for neutralization activity and flow cytometry. It is produced in hybridomas and purified by affinity chromatography with protein G.  Anti-hDectin-1-IgG recognizes hDectin-1 isoforms A and B. 

Dendritic cell-associated C-type lectin-1 (Dectin-1) is a C-type lectin receptor (CLR) that recognizes β-glucans, glucose polymers found in the cell walls of fungi, and thus plays an important role in antifungal innate immunity. Dectin-1  is encoded by the C-type lectin domain family 7 member A (CLEC7A) gene and alternatively spliced into 2 major isoforms: a full-length A isoform and a ‘stalkless’ B isoform, which do not induce the same response to soluble and particulate β-glucans [1, 2].

Dectin-1 is a member of the C-type lectin receptor (CLR) family and plays an important role in antifungal innate immunity. In humans and mice, it is alternatively spliced into two major isoforms, a full-length A isoform and a ‘stalkless’ B isoform [1, 2]. It is expressed on phagocytic cells, including macrophages and neutrophils.
Dectin-1 is a specific receptor for β-glucans [2]. β-Glucans are glucose polymers found in the cell wall of fungi, including the yeasts Saccharomyces cerevisiae and Candida albicans. Upon binding to its ligand, Dectin-1 triggers phagocytosis and signaling through the kinase Syk and the adaptors CARD9-Bcl10-Malt1 leading to the production of reactive oxygen species (ROS), activation of NF-κB and subsequent production of pro-inflammatory cytokines [3].
Notably, Dectin-1 signaling has been shown to collaborate with Toll‑like receptor 2 (TLR2) signaling to enhance the responses triggered by each receptor [4].
