" two major strategies for aseptic work are described: using a bunsen burner and using a laminar flow hood. disinfect the work space as in step 6. purchase sterile reagents when possible, only use under aseptic conditions in a culture hood to ensure they remain sterile. sterile capped tubes. use gloves, goggles, mask, and protective clothing as necessary. flame sterilize the opening of a vessel: 9. the handbook and videos provide an introduction to cell culture, with a focus on aseptic technique, microbial contamination, laboratory safety and cell culture experiments. glasses, or goggles. session id: : cea0bd32296fcb18efb57d2 player element id: performplayer. cell culture labs should be at least bsl- 2. to that aim, we have assembled this updated laboratory handbook of cell culture techniques. cell culture reagents, incubators and work surfaces are all sources of microbes, but by taking simple steps, it is possible to reduce the probability of contamination. adding cell culture to their repertoire of techniques expanding daily, we believe there are many who can benefit from sigma’ s and ecacc’ s combined knowledge and experience in cell culture. safety: protect eyes, mucous membranes, open cuts and wounds from contact with biohazard material. 0 introduction to 3d cell culture 30 12.
contamination prevention and aseptic technique 16 good aseptic technique make it difficult for microorganisms to invade culture vessels sealed cultured vessels vented cap flasks disposable aspirators cell culture hoods with good laminar flow do not use as a storage area! cell culture experiments, laboratory safety, aseptic technique, and microbial contamination of cell cultures, as well as providing basic methods for passaging, freezing, and thawing cultured cells. although cell culture can theoretically be carried out on an open bench. if an unintended microorganism is introduced into a pure culture, the culture becomes contaminated. 2 scale- up solutions 31 12. the elements of aseptic technique are a sterile work area, good personal hygiene, sterile reagents and media, and sterile.
purpose: to describe aseptic techniques used by cell culture specialists in handling products from and/ or mammalian cells. when the aseptic pdf task has been completed, promptly remove any larger contaminated items or other material meant for disposal ( e. aseptic technique is the collection of procedures and techniques designed to prevent the introduction of unwanted organisms into a pure culture or into the laboratory environment. 0 alternative cell culture systems 31 12. 3 roller bottle culture 31 12.
assorted sterile pipettes and pipetting device including multi- channel pipette. aseptic technique aseptic technique for cell culture pdf tips aseptic technique prevents contamination of cell cultures and reagents by microorganisms in the environment. sanitize gloves by spraying them with 70% alcohol and allowing to air dry for 30 seconds before commencing work. methods by which this may be achieved are described here, along with important characteristics of the environments and key equipment that facilitate sterility maintenance in modern laboratories and biopharmaceutical facilities. 0 authentication of cell lines 29 11. 6 aseptic technique and contamination control 27 9. , metabolic studies, aging), the effects of drugs and toxic compounds on the cells, and mutagenesis and carcinogenesis. cell culture cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells ( e. general example using dmem media media measure. put all materials and equipment into the cabinet prior to starting work. keywords: contamination; mycoplasma; retrovirus; str profiling; misidentification; cell authentication; conditional reprogramming. the culture and storage of mammalian cells must be carried out under conditions that exclude microorganisms. 7 what to do in the event of contamination 28 10. check pdf which culture media and culture supplements the cell line you are using requires before starting cultures. cryogenic vials centrifuge tubes liquid waste container.
