How is Gram staining done? What is the effect of pH in the germination of seeds? In the experiments done with laccase, describe the purpose of a spectrophotometer. Explain how gel electrophoresis works. When and why is acid stain used?
Explain how gel electrophoresis works. How do we use nitrogen in our biological processes? What are the three major steps in PCR and what happens in each step? What's PCR, How does it work, and what can it be used for? How do surfactants work?
Unlike traditional paints that form a hard barrier, ablative paint works through a process called “ablative action,” where the outer layer gradually wears away, releasing biocides that deter marine growth. This continuous wearing away of the paint helps to prevent the buildup of marine organisms ...
How Histology Works Courses in histology focus on the preparation of histology slides, relying on previous masteryof anatomy and physiology. Light andelectron microscopytechniques are usually taught separately. The five steps of preparing slides for histology are: Fixing Processing Embedding Sectioning Sta...
Figure 14. (a) A spectrophotometer is commonly used to measure the turbidity of a bacterial cell suspension as an indirect measure of cell density. (b) A spectrophotometer works by splitting white light from a source into a spectrum. The spectrophotometer allows choice of the wavelength of light...

Promega's Reaction Buffer C, supplied with SacII works well for both linear and supercoiled DNA substrates. The Table below lists the minimum number of units necessary to completely cut 1µg of a supercoiled pGEM® Vector containing a single recognition site. Commonly used Promega restriction ...
the pH of my lotions before adding this preservative. It works against a wide spectrum of bacteria and molds and can be used at a dosage of .2% in shampoo recipes or .3-1% in lotions and creams. This is the preservative I used when I made the video of myself making a basic lotion...

Staining is an important technique to highlight the structure of microorganisms, such as bacteria, under a microscope. Gram staining is a simple staining method that stains bacterial cells and categorizes them into gram-positive or gram-negative bacteria based on the amount of peptidoglycan in ...
