Step by step
Solved in 2 steps
- The functions of the loading dye are: (select all that apply) to prevent sample degradation as gel generates heat to make sure sample sinks to bottom of sample wells so that you can visualize the sample as it runs through the gel so that you can see your bands under UV lightWhy are there strict rules and policies when it comes to working in a laboratory? What would happen if you did not follow the guidelines? What could happen to the samples? The patient? What do you think would be the right course of action?Why do we need strict rules and policies while working in the laboratories
- What are the mechanisms of samples separation work in Thin layer Chromatography? Please shortly write at your own words. Answer should be to the point (5-6 lines maximum).Mary Jo prepared a series of diluted samples by taking 1 mL of sample and adding it to 4 mLs of diluent. She then diluted the sample further by adding 1 mL of diluted sample to 19 mLs of diluent. What is the final dilution factor ?What are the advantages and disadvantages of the filter method in the analysis of water samples? Why is the incubation temperature critical for this test?
