Abpromise guarantee covers the use of
in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1.25 µg/ml. Detects a band of approximately 54 kDa (predicted molecular weight: 52 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Use a concentration of 4 - 8 µg/ml.
Use at an assay dependent concentration.
ELISA titre using peptide based assay: 1/62500.
Component of the cleavage factor Im complex (CFIm) that plays a key role in pre-mRNA 3' processing. Binds to cleavage and polyadenylation RNA substrates.
Belongs to the RRM CPSF6/7 family.
Contains 1 RRM (RNA recognition motif) domain.
