Background Information

The C9orf72 "GGGGCC" repeat sequence codes five repeat peptide "GA repeat; GAGAGAGAGA", "GP repeat; GPGPGPGPG", "GR repeat; GRGRGRGRG", "AP repeat; APAPAPAPA" and "PR repeat; PRPRPRPRP". It was described previously that aggregated forms of poly-GA and poly-GP proteins do not enter the separation gel (PMID: 26374446). This antibody is used to detect the GR repeated sequence. The recombinant proteins GST-SNRPD1 and 6*His tag- SNRPD1 which contains the sequence “GRGRGRGRGRGRGRGRGR” were used to detect this antibody. Both proteins can be recognized by the antibody 23978-1-AP.
