pPICZaAPkrhdd-6xH

Short Description:"pPICZ α" refers to a vector containing the yeast alpha-factor signal peptide sequence, which aids in the proper secretion of proteins. It was developed by Invitrogen (now part of Thermo Fisher Scientific). "pPICZαA-PHDD-6xH" is a vector used for expressing the PHDD protein with a 6xHis tag in Pichia pastoris.

Gene Circuit Diagram:

AOX1 promoter α-factor secretion signal pPICZaAPkrhdd-6xH 6xHis AOX1 terminator

Description:

Choose the appropriate restriction enzymes to perform double digestion on the pPICZaA plasmid, generating sticky ends that match the target gene fragment (Pkrhdd) and the 6xHis tag sequence. Separate and purify the digested plasmid backbone. Perform a ligation reaction with the purified target gene fragment (Pkrhdd), the 6xHis tag sequence, and the digested pPICZaA plasmid backbone.

Result:

We are using chemical and electroporation methods to transform the pPICZaAPkrhdd-6xH into Pichia pastoris, and colonies have formed after cultivation, but there is no melanin expression after induction with methanol. This could be due to a failure in plasmid construction, or it could be due to other reasons.
