分子别名(Synonym):2B4,NAIL,NKR2B4,Nmrk,SLAMF4
种属(Species):Human
表达系统(Expressed Host):HEK293 Cells
产品状态(Buffer):Lyophilized from sterile PBS, pH 7.4
分子量(Molecule Mass):The recombinant 2B4/CD244/Fc chimera is a disulfide-linked homodimer. The reduced monomer comprises 438 amino acids and predicts a molecular mass of 49 kDa. As a result of glycosylation, the rh2B4/CD244/Fc monomer migrates as an approximately 70-80 kDa band in SDS-PAGE under reducing conditions.
内毒素(Endotoxin):<1.0 EU per μg by the LAL method.
生物活性(Activity):1. Measured by its binding ability in a functional ELISA. Immobilized human CD48 at 10 μg/ml (100 μl/well) can bind recombinant human 2B4 / CD244 with a linear range of 0.004-0.4 μg/ml.
表达区间(Protein Construction):A DNA sequence encoding the extracellular domain (Ser 2-Arg221) of human 2B4 / CD244 (NP_057466.1) precursor was expressed with the C-terminal fused Fc region of human IgG1.
存储条件(Storage): For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.
运输条件: In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Store it under sterile conditions at -20℃ to -80℃ upon receiving. Recommend to aliquot the protein into smaller quantic6ae6b7-92a2-4049-a34b-e7cc3839b466}䵄佉䤺㩄檻쬿▌䄃鎮♑뭂ݢ\Device\HarddiskVolume5\DosDevices\E:\??\Volume{cb3f6abb-258c-4103-ae93-512642bb6207}䵄佉䤺㩄蕾⬣뮊䰵ꢁ⓰싷銈\Device\HarddiskVolume6\??\Volume{2b23857e-bb8a-4c35-81a8-f024f7c28892}䵄佉䤺㩄㕦砣ᚑ䀭➻擨葅ᙕ\Device\HarddiskVolume1\??\Volume{78233566-1691-402d-bb27-e86445845516}
