BJ5183 Chemically Competent Cell

Culture medium	LB + 20mcg/ml streptomycin: LB + 20mcg/ml streptomycin: yeast extract 5.0g, peptone 10.0g,NaCl 10.0g, distilled water 1.0L,pH 7.0. Sterilization at 121 ℃ for 15min. After sterilization, streptomycin was added when the culture medium was cooled to 40-50 ℃ with a concentration of 20mcg/ml.
Subculture procedure	(1) Prepare a test tube containing 5~10mL of liquid medium and 2 plates; (2) Open it in the safety cabinet, heat the tip of ampoule in a flame, quickly drop sterile water to creak it, then break it with forceps; (3) draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; (4) inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; ⑤ Put all the liquid test tubes and plates under the above culture conditions for cultivation, and the strains can be used when they grow.
Growth conditions	37 ℃;18-24h; Aerobic;
Storage conditions	2-8 ℃
application	Scientific research, the most commonly used competent cells of the pre-adenovirus system.
Sharing mode	Public welfare sharing
