Yeast is a commonly used model organism, often used for genetic modification, and the yeast amino acid defect medium is the necessary medium for yeast transformation and yeast hybridization, its main use: for the experimental research of yeast single hybridization/yeast double hybridization, and the screening of yeast genetic mutant strains. According to the type of defective amino acids, it is divided into four categories of media, respectively, one deficiency, two deficiency, three deficiency, four deficiency media, the company can customize the relevant media according to your requirements, quality assurance.

A deficient medium: The SC-selected medium of such yeast represented by SD-ADE or the SD deficient medium is mainly used for the transformation screening of single plasmid yeast

Uses: expression of foreign genes in yeast, functional complementarity of heterologous genes, initial plasmid transformation in yeast single-hybrid system and yeast two-hybrid system.

e.g.:SD/-Trp, SD/-Leu, SD/-His, SD/-Ura, SD/-Met, SD/-Ade, SC-Trp, SC-Leu, SC-His, SC-Ura, SC-Met, SC-Ade

Precautions

1: The medium contains all the required ingredients (except glucose, because some researchers need to use other sugars such as galactose to induce GAL1 promoter expression), a fine mixture of various amino acids and yeast nitrogenous base/yeast nitrogen source dry powder, weighed at 8g/L, and then prepared into the corresponding culture solution after adding water. No need to purchase MinimalSDBase or other yeast nitrogen source ingredients. After autoclaving, sterile glucose is added until the final concentration is 2% (or raffinose) or the specific inducer required by the experiment (such as the dose or concentration of galactose for the induced expression of GAL1 promoter is 2%), which is suitable for the expression of foreign genes in yeast. Selective defect cultures such as yeastone-Hybrid and yeasttwo-Hybrid systems screen for yeast phenotypes containing specific marker genes.

2: When preparing yeast defect medium, glucose can be added first and then high-pressure, which will not have a serious impact on the growth of yeast. However, if the addition of glucose and then high-pressure disinfection, the medium will change color, ranging from light yellow to dark brown, and still have a certain effect on the growth of cells (but under normal circumstances will not affect the experiment). Suggestion: Since amino acids and glucose can react chemically under high temperature and high pressure, the technical department does not recommend adding glucose to the post-high pressure, but recommends using the method indicated above 1 to prepare.

3 Suggestion: In principle, raffinose and galactose can not be high temperature and high pressure, because their chemical structure will change under high temperature and high pressure, which will inhibit the induction effect, which reminds researchers to pay attention to, especially when doing expression regulation mediated functional complementarity experiments!

4: When preparing a plate, that is, a soft Agar semi-solid medium (Agar powder 2%, i.e., 2 grams of Agar powder per 100ml) for conversion screening, the pH needs to be adjusted to about 6.0 before high pressure (for convenience, the pH range can vary between 5.6 and 6.5), while the liquid medium does not need to be adjusted.
