We fused HA-tag with N-terminal of bglX gene on ZXFα-bglX vector. Label cells with Mouse Anti HA-Tag Polyclonal antibody and Fluorescein (FITC)–conjugated Affinipure Goat Anti-Mouse IgG(H+L). Result of flow cytometry analysis is as follows: fluorescence intensity x-mean value of Pichia pastoris with pPICZα empty vector is 0.306, with bglX-ZXFα is 23.4.
