General description

Purified mouse monoclonal antibody generated by immunizing BALB/c mice with the specified immunogen and fusing splenocytes with NS-1 mouse myeloma cells. Conjugated to agarose. Recognizes the exposed 5′ cap structure (2,2,7-trimethylguanosine) of small nuclear RNAs (snRNAs).
Recognizes the exposed 5′ cap structure (2,2,7-trimethylguanosine) of small nuclear RNAs (snRNAs). Also recognizes 7-methylguanosine-capped mRNA.
This Anti-2,2,7-Trimethylguanosine Mouse mAb (K121) Agarose Conjugate is validated for use in Affinity Purification, IP, IP, ICC, Paraffin Sections for the detection of 2,2,7-Trimethylguanosine.

Other Notes

Also recognizes 7-methylguanosine-capped mRNA. 2,2,7-trimethylguanosine (Ab-1) is human, mouse, and rat reactive. This antibody reacts with the exposed 5′ cap structure of the snRNAs and the antibody can be used for the purification of snRNPs by immunoaffinity chromatography. All of the major snRNPs bind to the monoclonal antibody column and can be gently eluted by washing with 7-methyl guanosine. Antibody should be titrated for optimal results in individual sample types.
