Do you have an antibody for Western Blot Analysis of MAPK1 gene knockdown using your MAPK1 control siRNA?

Yes. The Human and Mouse MAPK1 protein (also called MAPK2 or Erk2, GenBank accession numbers NM_002745 [human] and NM_011949 [mouse]) can be easily detected by western blotting using the MAPK1-specific Tag-100 Antibody. The Tag-100 Antibody was originally developed for detection of proteins expressed using QIAGEN’s pQE-100 DoubleTag Vector. It is also effective for monitoring gene silencing of human and mouse MAPK1 at the protein level since the Tag-100 epitope that it detects is derived from MAP Kinase.

Hs/Mm_MAPK1 control siRNA is one of QIAGEN's Control siRNAs, and is also included as a positive control in the RNAi Human/Mouse Starter Kit.
