OriGene overexpression protein microarray chip was immunostained with ultraMAB anti-FOLH1 mouse monoclonal antibody (Clone UMAB25). The positive reactive proteins are highlighted with two red arrows in the enlarged subarray. All the positive controls spotted in this subarray are also labeled for clarification. These data show that ultraMAB anti-FOLH1 (Clone UMAB25) very specifically recognizes FOLH1 antigen on OriGene protein microarray chip.
