We provide various purification services, including but not limited to affinity purification, ion-column purification, hydrophobic packing purification, and molecular sieve purification. Subsequently, we provide identification and quantification for proteins by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), western blot, mass spectrometry, etc. In addition, if clients need to conduct functional and applied studies on the obtained α-linked galactose-binding lectins, such as enzyme activity determination, structural analysis, or interaction study, our professional team's relevant personalized services.

Paper Title: Expression of frutalin, an α-D-galactose-binding jacalin-related lectin, in the yeast Pichia pastoris
Expression System: Yeast-Pichia pastoris
Journal: Protein Expression and Purification
Published: 2008
Results: The recombinant protein was directed to be secreted by optimized cloning of the coding mature sequence into the pPICZαA expression vector, which was applied to protein expression in Pichia pastoris. The soluble recombinant protein was successfully detected in the supernatant. Frutalin was found to be expressed as a single chain by SDS-PAGE and Edman degradation analysis. In addition, a terminal repeat sequence was found possibly due to incomplete signal sequence processing. Recombinant frutalin bound specifically to the monosaccharide Me-α-galactose and had similar binding properties to natural lectin. Showed that Pichia pastoris was an excellent host for the expression of recombinant lectins.
