Figure 6From: Generation and functional characterization of the anti-transferrin receptor single-chain antibody-GAL4 (TfRscFv-GAL4) fusion proteinDetection of GAL4 DNA binding domain in TfRscFv-GAL4 with ELISA. TfRscFv-GAL4 was coated in the 96 well plates at different concentration, GAL4 protein was used a positive control. The absorption of OD495 nm was used for the detection of yellow products of OPD reacted by HRP.Back to article page
