What are the main sources of contamination in cell culture?
Contamination can arise from bacteria, mold, or mycoplasma, which negatively impact cell viability.
How often should lab personnel receive training?
Lab personnel should be trained at least once a year on proper cell culture techniques.
What protective clothing is recommended in cell culture?
A clean lab coat designated for cell culture use and new nitrile powder-free gloves are recommended.
How should surfaces be prepared before cell culture work?
Surfaces should be sprayed with 70% ethanol and wiped down with a lint-free paper towel.
What is a biological safety cabinet?
It is a specialized workspace that provides a sterile environment to minimize contamination during cell culture work.
Why is it important to avoid reaching over open bottles?
Reaching over open bottles can lead to contamination from gloves or sleeves, affecting the cell culture.
What should be done with serological pipettes if they touch contaminated surfaces?
They should be discarded to prevent contamination of the culture.
