LILRB4/CD85k/ILT3 Protein, Human, Recombinant (hFc)
(Synonyms: LIR5, LILRB4, ILT-3, ILT3, HM18, CD85K) Copy Product InfoSynonyms: LIR5, LILRB4, ILT-3, ILT3, HM18, CD85K
Catalog No. TMPK-00603 Copy Product Info
LILRB4,also known as CD85k and LIR-5, ILT3, is an approximately 60 kDa transmembrane glycoprotein that negatively regulates immune cell activation. Mature human ILT3 consists of a 238 amino acid (aa) extracellular domain with two Ig-like domains, a 21 aa transmembrane segment, and a 168 aa cytoplasmic domain with 3 immunoreceptor tyrosine-based inhibitory motifs (ITIM).LILRB4 is receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. LILRB4/CD85k/ILT3 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with C-hFc tag. The predicted molecular weight is 52.6 kDa and the accession number is AAH26309.

| Species | Human |
| Expression System | HEK293 Cells |
| Tag | C-hFc |
| Accession Number | AAH26309 |
| Construction | Gln22-Arg256 |
| Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | LIR5, LILRB4, ILT-3, ILT3, HM18, CD85K |
| Research Background |
| Molecular Weight | 52.6 kDa (predicted). Due to glycosylation, the protein migrates to 60-68 kDa based on Tris-Bis PAGE result. |
| Storage | Store at low temperature Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
