"m1G related antibodies" refer to antibodies that are specifically designed to target and bind to a modified nucleotide known as "m1G" in RNA molecules. m1G stands for "1-methylguanosine," which is a chemically modified form of the guanosine base found in RNA. In RNA molecules, guanosine (G) is one of the four nucleotide bases that make up the genetic code. However, in certain cases, RNA can undergo chemical modifications, such as the addition of a methyl group to the guanosine base, resulting in 1-methylguanosine (m1G).
