Beschreibung

Allgemeine Beschreibung

This plasmid is designed to express tagged proteins in yeast cells (Saccharomyces cerevisiae). The plasmid contains an auxotrophic Uracil selection expression cassette (URA3) that allows for the positive selection of yeast that are deficient in the URA3 gene (YEL021W). This is typically achieved by growing the yeast in minimal media that is reconstituted with the essential amino acids and nucleotides but excluding Uracil.

About the Peptide Tag:This plasmid contains an full length Alpha Factor (A-FactorFL) secretory peptide to allow proteins to be exported from the cytosol. Alpha factor is an endogenous yeast protein that is naturally secreted into the supernatant. The wild-type Alpha Factor protein contains a series of repeating protein sequences that are cleaved out by cellular proteases that recognise a specific site. This produces a series of small peptides that contain the mature alpha peptide sequence. This plasmid contain the wild-type signal peptide from the full length Alpha factor gene but also the coding sequence that leads up to the first endogenous protease cleavage site. The addition of these sequences has been demonstrated to provide more consistent secretion of proteins in comparison to using just the signal peptide alone. All of the wild-type protein sequences will be removed during protein maturation and export by endogenous proteases. This plasmid also contains a secondary Deca-Histidine (10His) protein tag. The sequence of this tag is: HHHHHHHHHHWe provide a range of dual peptide tag plasmids. This is because some peptide tags provide specific biological properties (e. g., small molecule affinity new epitopes solubility or protein secretion) that are not provided by others.

Promoter Expression Level: This plasmid contains the Yeast Elongation Factor Alpha promoter (TEF1). This is the strongest of the yeast promoters that we sell. It is a constitutive promoter and requires no induction. If you are interested in weaker promoters levels than we also stock plasmids that contain the following promoters in order of decreasing strength TPI (strong), ADHI (medium), STE5 (weak). We also stock Galactose inducible promoter plasmids if inducible expression is required. Please contact us for further information.
