Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

31C4 was isolated during a screen for monoclonal antibodies reactive with yeast nucleolar proteins. We determined the specificity by screening a yeast genomic library expressed as b-galactosidase fusion proteins in lgt11. Two individually isolated, different positive clones were found. Sequencing revealed that in both clones b-galactosidase was fused at the EcoRI site to the amino acid sequence beginning with EFEH, corresponding to amino acids 190 and onwards in Nsr1p. This peptide is ~20 amino acids into the first RRM domain. Thus, reacts with an epitope in the C-terminal 55% of Nsr1p. The antibody is provided as sterile-filtered cell culture fluid from an Integra CL-350 biochamber plus sodium azide. The IgG isotype and exact concentration are not known.
