• 

  ELISA experiment of compound using 68302-1-Ig

  Indirect ELISA and competitive ELISA results show that this antibody is specific to m7G. Indirect ELISA (blue curve, refer to top X-right Y axis) was performed by coating BSA conjugated m7G at 10ng/well followed by blocking with 1% BSA. Serial diluted primary antibody was added to the plates and incubated at 37℃. HRP-goat anti-mouse was used for detection. Competitive ELISA was performed similarly except that different concentration of m7G or its structure analogue compound Guanosine was mixed in 20ng/mL primary antibody (red curve, refer to bottom X-left Y axis).

• 

  Dot Blot experiment of HeLa using 68302-1-Ig

  Total RNA was isolated from HeLa cell line and was dotted to NC membrane at different amount as indicated above the dots. The membrane was blocked with BSA and blotted with m7G antibody 68302-1-Ig at 1:5000 followed by incubation of HRP-goat anti-mouse secondary antibody. Signal was developed by ECL substrate. A parallel dot blot was performed using Mouse IgG2b isotype control Monoclonal antibody 66360-3-Ig at the same dose.

Background Information

7-Methylguanosine (m7G) is a modified purine nucleoside. It is a methylated version of guanosine and when found in human urine, it may be a biomarker of some types of cancer. In the RNAs, 7-methylguanosine have been used to study and examine the reaction evolving methylguanosine. It also plays a role in mRNA as a blocking group at its 5´-end. The m7G modification actively participates in biological and pathological functions by affecting the metabolism of various RNA molecules, including messenger RNA, ribosomal RNA, microRNA, and transfer RNA. Increasing evidence indicates a critical role for m7G in human disease development, especially cancer, and aberrant m7G levels are closely associated with tumorigenesis and progression via regulation of the expression of multiple oncogenes and tumor suppressor genes.
