A simple nuclear staining takes place for 10 minutes at room temperature with Hoechst or DAPI diluted in PBS. After completing the IF procedure, the samples must be mounted to be suitable for microscopy. For this purpose a mounting medium (e.g. Mowiol or Prolong Gold) is used which fixes ...
How to Prepare 5M HCl in the Lab The most common reason you will need to handle HCl is when you prepare 5M HCl for your lab to adjust the pH of solutions. Let’s go through how to do this. Firstly, here are a few facts:
In a fume hood place the sapphire disks in concentrated hydrochloric acid (HCl 30%) for 2 h. Wash the sapphire disks 3x for 5 min with doubly distilled (dd) H20. Let the sapphire disks dry on filter paper afterwards. After the cleaning process, a finder grid pattern needs to be...
