General description
M9基础培养基是一种广泛引用的大肠杆菌培养用微生物生长培养基。 这种基础微生物缓冲培养基只含有盐和氮,所以以往往往补充葡萄糖、氨基酸和维生素。
Preparation Note
1.取56.4 g溶于1L蒸馏水中。
2.121°C下高压灭菌15分钟。
这种方便的5x浓缩液可根据需要存储和稀释,足够制备5L 1x M9基础盐。
对于M9基础培养基:
1.无菌稀释200 ml M9基础盐,用800 ml无菌水稀释5倍。如有必要,冷却至45-50°C。
2.无菌加入20 ml无菌1 M葡萄糖和2 ml无菌1 M硫酸镁,制备1 L M9基础培养基。
3.如有需要,向M9基础培养基中无菌添加0.1 ml 1 M无菌氯化钙。M9基础培养基也可补充适当的氨基酸。
2.121°C下高压灭菌15分钟。

通过向1L水中搅拌加入56.4粉末可制备5x浓缩储备溶液。 在121°C下高温灭菌15分钟以灭菌。 使溶液冷却后再添加其他成分,如抗生素(若需要)。
通过向800mL无菌水中加入200mL的5x M9储备溶液,即可稀释5x M9浓缩储备溶液而制备得到1x工作溶液。 如有必要,使溶液冷却后再添加其他成分,如抗生素(若需要)。

Balancing protein expression is critical when optimizing genetic systems. Typically, this requires library construction to vary the genetic parts controlling each gene, which can be expensive and time-consuming. Here, we develop sRNAs corresponding to 15nt 'target' sequences that can be

Mycobacterium tuberculosis ( Mtb) produces a number of sulfur-containing metabolites that contribute to its pathogenesis and ability to survive in the host. These metabolites are products of the sulfate assimilation pathway. CysQ, a 3'-phosphoadenosine-5'-phosphatase, is considered an important regulator of

Biochemical pathways are often genetically encoded as simple transcription regulation networks, where one transcription factor regulates the expression of multiple genes in a pathway. The relative timing of each promoter's activation and shut-off within the network can impact physiology. In
