After writing for a month I’ve gotten my first reader question and I’m excited to share the answer with the rest of you. Here’s the question I got a week ago from a reader working in a tissue bank regarding their samples:

I work in a tissue bank and have some concerns in the practice we use for handling our tissue. When the tissue is ready for processing we receive it in a partially frozen state. To thaw, we have the tissue soak in sterile water for a period of 15 min. We process in rooms with air exchanges that are similar to a hospitals OR. We do have preventative measures after the process we take to protect the tissue. However, we recently have been trying to accommodate clients by processing aseptically. My question is, can the use of water create a harbor for bacterial growth considering the length of time the tissue will remain in the room throughout the duration of the process. (8 to 16 hours) and would there be any alternative means of a safer way in which to thaw the tissue?                                                                                                                -G

 This is a great question but a little bit outside of lab work that I’m personally familiar with. Thankfully though, aseptic technique works the same way everywhere, so here are some suggestions I came up with based on my experience. Continue reading Ask A Microbiologist #1
