Protein DetailsPurity >90% by SDS Page and analyzed by silver stain. Endotoxin Level <0.1 ng per 1 µg as determined by the LAL method Protein Accession No. N-terminal Sequence Analysis Leu22 (pro) & His (mature) State of Matter Lyophilized Predicted Molecular Mass By N-terminal sequencing, two peptides corresponding to mouse Lefty-1 propeptide (with Leu 22 at the amino-terminus) and mature Lefty-1 (with a histidine residue at the amino-terminus) are present in the recombinant preparation. In SDS-PAGE under reducing conditions, the propeptide and
mature Lefty-1 have apparent molecular masses of 12 kDa and 36 kDa, respectively. The two peptides apparently remained associated after processing and during protein purification. Storage and Stability This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.
