Pichia Pastoris Surface Display Kit for Protein Expression and Antibody Screening

Product Overview

The Pichia Pastoris Surface Display Kit leverages the α-agglutinin system to efficiently display exogenous proteins on the yeast cell surface. The fusion protein 

is non-covalently attached to the cell wall of Pichia pastoris. After the target protein is expressed as a fusion with Aga2p, it is secreted into the extracellular space. The Aga2p subunit forms two disulfide bonds with the Aga1p subunit, and the Aga1p subunit is covalently anchored to the yeast cell wall via β-glucan, firmly 

displaying the protein on the surface. This robust Pichia pastoris expression system is ideal for efficient protein expression and antibody screening.

This kit includes the essential components for successful protein expression, including the X33 strain, the pPICZaA-Aga2p vector, and a positive control strain. 

With this complete system, researchers can easily express and display proteins on the surface of Pichia pastoris for various applications, from protein interaction 

studies to antibody discovery.

FAQs

Q1: What is the Pichia Pastoris surface display system used for? 
A1: The Pichia Pastoris surface display system is designed for efficient protein expression and antibody screening, enabling the display of exogenous 

proteins on the yeast cell surface.

Q2: Can this kit be used for antibody screening? 
A2: Yes, this kit is perfect for antibody screening, as it allows researchers to test and identify specific antibodies against target proteins.

Q3: What is the size of the target protein expressed using this system? 
A3: The target protein expressed with the X33 pPICZaA-Aga2p positive control has a size of approximately 52 kDa.

Q4: Why are YPG and BMMY media used in the Pichia pastoris surface display system? 
A4: The reason lies in the AOX1 promoter. In the presence of glucose, the transcription of the AOX1 promoter is inhibited. However, when methanol is used as 

the sole carbon source, the AOX1 gene in the host strain is strongly induced, leading to a high level of expression of the target gene. Therefore, during induction, 

it is necessary to remove glucose from the media and supplement methanol daily to compensate for its consumption and evaporation during the induction period.
