The gel shows non specific pcr product , these may occur due to DAN contamination ( during lab work,or DNA not free from proteins and RNase). Water not free contamination.To aviody these ensure sterlie condition in lab when you are working, use gloves etc.ensure DNA free contamination.Correct amont of master mix.If don't get result in repeated attempts please change the master mix (previously used).
what do you think she should change in her protocol to avoid the problem ? Problem.3:...
solve for gel preparation and PCR mastermix calculations with steps for understanding TBE Buffer Calculations Determine the mass of the following reagents for a 10X stock 700mM of Tris Base (157g/mol) 887mM of Boric Acid (62g/mol) 25.7mM of EDTA (292g/mol) Dissolve in 750ml of DIH.O and bring to volume (IL) Calculate the dilution of your 10x stock for a 1X working stock. Remember you only need IL of working stock for a single experiment. Gel Preparation Calculations You need to...
