Hi All,
I feel a bit silly asking this, but it could potentially save 3-4 hours of my day re-pouring new plates. I forgot to add KHPO4 to my NGM mix after autoclaving (I made 500mL, so needed to add 12.5mL KHPO4, all other additives are in there). Question - can I still add filter sterilized KHPO4 in the hood to individual plates and use them? (each plate contains 10mL of NGM, so I would add .25mL of KHPO4 to each plate - a pain, but a smaller pain than re-pouring new plates). I don’t know if the KHPO4 would diffuse the same way into solid NGM as it would into the molten, liquid NGM? Or should I just toss the plates and start over?
Thanks,
B
