CSM-URA培养基(粉末)

CSM-URA培养基(粉末)

CN¥1,017.10
氨基酸组分混合物(CSM),不含尿嘧啶。用于酿酒酵母生长培养基。

SKU: 114511212-CF

Synonyms
Complete Supplement Mixture
Product Description

Single dropout formulation ( without Uracil) of Complete Supplement Mixture (CSM) of amino acids for S. cerevisiae growth media. Time tested formulation is available in complete and dropout formulations.

Application Notes

The selection of plasmids in yeast is based on the use of auxotrophic mutant strains that cannot grow without a specific media component (an amino acid, purine or pyrimidine). Transformation with a plasmid containing the mutated gene enables the transformant to grow on a medium lacking the required component. This CSM-Dropout medium create a richer medium for better yield and growth rate, and increase the probability of successful transformations when screening libraries or performing gene knock-outs.

Usage Statement

Unless specified otherwise, MP Biomedical's products are for research or further manufacturing use only, not for direct human use. For more information, please contact our customer service department.

CSM formulations are available that contain 20 or 40 mg/liter adenine. **80mg/liter of DL-Homoserine is substituted for L-Threonine in mixtures where L-Methionine is dropped out.
Grade Molecular Biology Certified™
Media Type Yeast CSM
Personal Protective Equipment Personal Protective Equipment Respiratory protection: Breathing apparatus only if aerosol or dust is formed. Hand protection: PVC or other plastic material gloves Skin and body protection: Usual safety precautions while handling the product will provide adequate protection against this potential effect. Eye protection: Safety glasses with side-shields Hygiene measures: Handle in accordance with good industrial hygiene and safety practice
pH pH Range (with DOB, after autoclave): 4.0 - 4.8 at 25 °C
Preparation Method Reagents are tested and chosen for their ability to promote optimum growth of yeast strains when combined in the DOB or DOBA with CSM or CSM-Dropout formula. DOB (Drop Out Base) is 1.7g Yeast Nitrogen Base, 5g Ammonium Sulfate, 20g Dextrose per liter. DOBA is DOB with 17% agar. Chosen reagents are combined in the proper proportions according to the formulation listed in the certificate of analysis and milled to a powder which thoroughly blends the reagents for uniform distribution. A sample of the milled and blended formulation was used to prepare liquid plate medium by adding 43.7g DOBA powder and 0.79g of CSM or the appropriate weight of CSM-Dropout to a liter of purified water. The combinations were mixed by hand for about 1 minute to dissolve the dextrose and autoclaved at 121 °C for 25 minutes. After cooling to 50 °C plates were poured.
Solubility Soluble in water.
Sterilization of Solutions Autoclave at 121 °C for 15 minutes
