The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 68 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Use at an assay dependent concentration.
ELISA titre using peptide based assay, 1:312500.
SF1 contains 1 KH domain, 1 CCHC type zinc finger, a nuclear transport domain and glutamine and proline rich regions. It is necessary for the ATP dependent first step of spliceosome assembly and binds to the intron branch point sequence (BPS) 5' UACUAAC 3' of the pre mRNA. It may act as transcription repressor. There are 6 named isoforms produced by alternative splicing.
