LILRA4, also known as ILT7 and CD85g, is an approximately 60-70 kDa variably glycosylated transmembrane protein that regulates immune cell activation. LILRA4 function coreceptor to limit the innate immune responses to viral infections; signaling occurs via FCER1G. 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. Specifications Synonyms CD85g; ILT7; ILT-7; ILT7MGC129598; LILRA4; MGC129597 Uniprot No. P59901 Source Recombinant Biotinylated Human LILRA4/CD85g Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Glu24-Asn446. Molecular Weight The protein has a predicted MW of 49.5 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% as determined by SDS-PAGE and HPLC Endotoxin < 1.0 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100μg/mL is recommended. Dissolve the lyophilized protein in distilled water. Storage The products are shipped with ice pack and can be stored at -20℃ for 1 year. 2-7 days, 2 to 8 °C under sterile conditions after reconstitution.3 -6 months, -20 to -80°C under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles. Note 1. For your safety and health, please wear lab coats and disposable gloves for operation. 2. For research use only! Product Data
