CD27 ligand (CD27L), also named CD70, is a type II transmembrane glycoprotein belonging to the TNF superfamily (TNFSF) and has been designated TNFSF7. Human and mouse CD27L share approximated 56% aa sequence identity. CD27L is expected to exist as non-covalent homotrimers. CD70 is constitutively expressed on medullary thymic epithelial cells (mTECs) in human and mouse. CD70 is also exclusively expressed on DCs, B cells, conventional- and regulatory T cells and NK cells but only after their activation. Specifications Synonyms CD70 molecule; CD70; TNFSF7; CD27 Ligand; CD27-L; CD27LG; Ki-24 antigen; TNFSF7G Uniprot No. P32970-1 Source Recombinant Biotinylated Human CD27 Ligand/CD70 Trimer Protein is expressed from HEK293 Cells with His tag at the N-terminal. It contains Leu50-Pro193. Molecular Weight The protein has a predicted MW of 51.8 kDa. Due to glycosylation, the protein migrates to 62-70 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 1 μg of the protein by the LAL method. Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/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.
