Cynomolgus LILRA4/CD85g Protein

Product Info

Recombinant Cynomolgus LILRA4/CD85g Protein is expressed from Expi293 with His tag at the C-terminal. It contains Glu24-Asn446.[Accession | A0A2K5UGH3]

Molecular Weight

The protein has a predicted MW of 47.7 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result.


Less than 1EU per μg by the LAL method.


> 95% as determined by Tris-Bis PAGE


Supplied as 0.22μm filtered solution in PBS (pH 7.4).


The product should be stored at -70℃. Please do not repeated freeze-thaw cycles.

Assay Data
Tris-Bis PAGE

Cynomolgus LILRA4/CD85g on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.


LILRA4, also known as ILT7 and CD85g, is an approximately 60-70 kDa variably glycosylated transmembrane protein that regulates immune cell activation. Mature human LILRA4 consists of a 423 amino acid (aa) extracellular domain (ECD) with four immunoglobulin-like domains, a 21 aa transmembrane segment, and a 32 aa cytoplasmic domain.LILRA4 function coreceptor to limit the innate immune responses to viral infections; signaling occurs via FCER1G (PubMed:16735691, PubMed:19564354). Down-regulates the production of IFNA1, IFNA2, IFNA4, IFNB1 and TNF by plasmacytoid dendritic cells that have been exposed to influenza virus or cytidine-phosphate-guanosine (CpG) dinucleotides, indicating it functions as negative regulator of TLR7 and TLR9 signaling cascades.
