What else can I help you with?
What food can methylene blue be used in to detect bacteria quickly?
Methylene blue reduction is the method used to measure the bacterial density in milk. The test is evaluated in term of the amount of time required from introduction of the blue until the milk turns white.
Which of the availble stain enhance your observation the most methylene blue or iodide?
Methylene blue would enhance your observation more than iodide staining. Methylene blue binds to nucleic acids and proteins, making them more visible under a microscope. Iodide staining is primarily used for visualizing lipids in samples such as plant tissues.
What is the function of PBS buffer?
PBS buffer (phosphate-buffered saline) is commonly used in biological and biochemical experiments to maintain the pH of a solution and provide essential ions for cell function. It is often used for washing cells, diluting antibodies, and preparing samples for analysis. PBS buffer helps maintain the stability and integrity of biological samples by providing a suitable environment for cells or proteins.
What the function of wash solution?
The function of a wash solution is to remove impurities, contaminants, or unbound materials from a sample or surface during laboratory procedures. It helps to enhance the accuracy and reliability of experimental results by ensuring that only the desired components remain after washing. Additionally, wash solutions can help maintain the stability of biological samples and improve the overall efficiency of assays or reactions.
What is the function of Bunsen?
The Bunsen burner is used for heating samples in laboratories.
Why do scientists collect and test air samples?
Scientists collect and test air sample because they want to see how clean/polluted it is. Then they can raise awareness to people if needed.
What is the function of comb in electrophoresis?
The comb is used to create wells in the gel where samples can be loaded for electrophoresis. It helps to organize the samples and ensure that they are separated properly during the process.
What is the function of methanol in the wright's stain solution?
Methanol is used in Wright's stain solution as a solvent to help dissolve the dyes and facilitate their penetration into cells, tissues, or other biological samples for staining purposes. It also helps to fix the stain onto the sample by enhancing the adhesion of the dye to the cellular components.
What is the purpose of adding methylene blue to the specimen?
Methylene blue is commonly used as a staining agent in microscopy to enhance the visibility of cellular structures within a specimen. It binds to nucleic acids and certain proteins, allowing for better contrast against the background, which aids in identifying and distinguishing various cellular components. Additionally, methylene blue can help highlight live versus dead cells, as viable cells may retain the dye differently compared to non-viable ones. Overall, its primary purpose is to facilitate clearer observation and analysis of biological samples.
Why is EMB formulation desirable?
EMB (Eosin Methylene Blue) agar is a selective and differential medium used for the isolation of fecal coliforms from water samples. The dyes eosin and methylene blue inhibit the growth of Gram-positive bacteria, allowing for the selective growth of Gram-negative bacteria such as E. coli. The formulation also allows for the differentiation of lactose fermenters (pink/purple colonies) from non-lactose fermenters (colorless colonies).
Samples of homogenous mixtures?
The examples of homogenous mixtures are table salt,table sugar,brass,air,sodium chloride solution,sugar solution,brandy and wines.that is all I got.
Where can we get free baby samples?
If the person have a internet connection they can enter all the baby food pages and ask for samples to try. They send them for free. The other solution is going to the store and buy little packages to try the food.
