Full Product Name: Human Interleukin-29 (IL-29)/Interferon Lambda 1, carrier-free
Formulation | Supplied lyophilized without a carrier protein |
Molecular Weight | Based on N-terminal sequencing, the mature recombinant IL-29 starts at Gly 20 and has a calculated molecular mass of 21.4 kDa. As a result of glycosylation, the recombinant monomer migrates as an approximately 26-35 kDa protein in SDS-PAGE under reducing conditions. |
Source | DNA sequence encoding the signal peptide from human CD33 was fused to the carboxyl terminally polyhistidine-tagged mature human IL-29 (Gly 20-Thr 200). The chimeric protein was expressed in a mouse myeloma cell line, NS0. |
