Question (57747) | GST 6XHis-tag ELISA Kit (ab128573)

Dear sir, I just placed an order of your 6xHis-tag ELISA kit (ab 128573). Can the kit be used to detect a his-tagged protein? My recombinant protein does not have any GST. From what described in the kit booklet, it seems can, but I want to confirm it. Thanks!
