How do you isolate gram negative bacteria?
MacConkey and blood agar are usually used to isolate gram-negative bacteria, which usually grow within 24 to 48 hours and are subsequently differentiated on the basis of colony morphology and biochemical reactions.
Why is pH important for cell culture?
Changes in pH in the cell culture environment can alter virtually every cellular process like metabolism, cell growth, and membrane potential. Extracellular pH is slightly alkaline and typically 7.3-7.4, while intracellular pH is slightly lower at 7.2.wafer probe
How does work?
Micromanipulation uses microsurgical techniques to study and alter the structure or composition of single living cells or a group of cells under a microscope.

Are narcissists usually cheaters?
Not all people with narcissistic personality traits are unfaithful in their relationships, but narcissism may naturally make cheating more likely. Serial cheating, having multiple partners, and increasing cruelty are all narcissist cheating patterns to be aware of.
Can I use DMEM instead of EMEM?
EMEM contains minimum concentrations of nutrients required for cell growth in culture while DMEM is a much more complex media with increased concentration of media components. Moreover, DMEM includes more substitutes that increase the nutrient condition of the media. So, there is no harm in shifting from EMEM to DMEM.
Can a narcissist ever change?

What is microinjection used for?
Microinjection is a method for mechanically injecting cells, genetic material, peptides, drugs, or other exogenous agents directly into cells or tissues using a very small pipette. Conversely, material may also be removed from the sample (e.g., enucleation of cells).
Who invented agar?
microbiologist Walther HesseAgar was first described for use in microbiology in 1882 by the German microbiologist Walther Hesse, an assistant working in Robert Koch's laboratory, on the suggestion of his wife Fanny Hesse.
