Fig. 1 Immunofluorescence labeling of transformed cells: green fluorescence corresponds to cells labeled with Mouse Anti HA-Tag Polyclonal antibody and (Fluorescein (FITC)–conjugated Affinipure Goat Anti-Mouse IgG(H+L), and red fluorescence corresponds to cells labeled with Rabbit Anti Flag-Tag Polyclonal antibody and Goat Anti Rabbit RPE Polyclonal antibody.

Immunofluorescence analysis of β-glucosidase surface display Pichia pastoris using flow cytometry.

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.
