Why are some cell culture media better than others?
Welcome to Osmolality.com | Osmolality | FAQMedia originally used for growth of mammalian cells were based on biological fluids, such as plasma. This type of media suffered many disadvantages including batch variation and vulnerability to contamination.
Related QuestionsHow can cell culture media be made?
Welcome to Osmolality.com | Osmolality | FAQA bioreactor allows the growth of human tissues outside of the body that amass and behave like those in the body. Another is the Rotary Cell Culture System, as it provides a gentler environment than a dynamic or static tissue culture system, thereby allowing cells to aggregate, grow 3-dimensionally, and differentiate. The result will be cells or tissues that closely resemble the in vivo tissue equivalent.
Related QuestionsBack to top Why is it important to limit exposure of cell culture media to fluorescent lights?
ATCC: Frequently Asked QuestionsAnswer: An important but often overlooked source of chemical contamination results from the exposure of media containing riboflavin or tryptophan to normal fluorescent lighting (see references below). These media components are photoactivated by UV radiation emitted from most fluorescent lights and give rise to hydrogen peroxide. This generates free radicals that are toxic to cells; the longer the exposure the greater the toxicity.
Related QuestionsBack to top What should the osmolality of my cell culture medium be?
ATCC: Frequently Asked QuestionsAnswer: Most established vertebrate lines will tolerate a rather large variation in osmotic pressure. The useful range of osmolality of cell culture media for vertebrate lines is between 260 to 320 mOSM/kg. Invertebrate lines vary greatly in their sensitivity to osmotic pressure. For example, the snail embryo ATCC CRL-1494 requires medium of about 155 mOSM/kg, while some insect media prefer 360 to 375 mOSM/kg.
Related QuestionsBack to top Can I use HEPES buffer in my cell culture medium?
ATCC: Frequently Asked QuestionsAnswer: HEPES and other organic buffers can be used effectively with many cell lines (see Shipman, C. (1969) Proc. Soc. Exp. Biol. Med. 130: 305). However, be aware that the compound can be toxic, especially for some differentiated cell types, so its effects should be evaluated before routine use (People, C.A., et al., (1982) In Vitro 18: 755). HEPES has also been shown to greatly increase the sensitivity of media to the phototoxic effects induced by exposure to fluorescent light. [Zigler, J.S.

Related QuestionsBack to top How can I adapt a monolayer cell line to grow in suspension culture?
ATCC: Frequently Asked QuestionsAnswer: Not all cell lines can be adapted to suspension growth. In general, normal diploid anchorage-dependent (must be attached to a substrate to grow) cells cannot be adapted without the use of microcarrier beads to which they can attach. Lines such as L-929 (ATCC CCL-1) and HeLa (ATCC CCL-2) which are not anchorage-dependent can be adapted and variants that grow in suspension already exist.
Related QuestionsBack to top What are the recommended carbon dioxide (CO2) levels needed to grow a cell culture?
ATCC: Frequently Asked QuestionsAnswer: While the levels of carbon dioxide in cell culture systems vary from that in ambient air (about 0.03%) up to 40% in air, generally either no added CO2 or 5% to 10% CO2 in air are the most frequently used. It is very important to adjust the concentration of sodium bicarbonate used in a medium to that required for equilibration with the level of CO2 used in the gas phase. Cells in culture produce CO2 and require small amounts of the compound for growth and survival.
Related QuestionsBack to top Can antibiotics and/or antimycotic agents be added to the cell culture medium?
ATCC: Frequently Asked QuestionsAnswer: Most cell culture technologists avoid using antibiotics for routine culture work. Antibiotics may mask contamination by susceptible bacteria and fungi while permitting mycoplasma to flourish unnoticed. Antibiotics may interfere with the metabolism of sensitive cells in culture. However, one may elect to introduce antibiotics for short periods to primary cultures or as a safeguard while propagating specific valuable stocks (e.g.

Related QuestionsBack to top Are there tissue culture media that do not require using a CO2 incubator?
ATCC: Frequently Asked QuestionsAnswer: Some cell lines may be maintained satisfactorily on an alternative medium such as CRCM-30 (Macy, M.L., and Shannon, J.E. (1977) TCA Manual 1: 3), L-15 medium, or CO2-independent medium (GIBCO BRL Cat. No. 18045) which do not require CO2 in the gas phase. You can usually determine if a medium is satisfactory by using it with the cell line in question for 3 to 5 passages. However, cultures established at very low concentrations (e.g., cloning) usually require CO2 in the gas phase.

Center for Relationship Abuse Awareness: Frequently Asked Qu...All cultures have both traditions of resistance to domestic violence as well as forms of acceptance of it. Culture cannot excuse domestic violence—though abusers may use “culture” as a way to justify their choice to abuse. Unfortunately, relationship abuse is prevalent in all cultures—. Across the world, different cultures may have different responses to domestic violence, and some may hold abusers more accountable than others.
Related QuestionsWhat is toxicity of beads in relation to cells and cell culture?
Seradyn | Technical Support | FAQThe concern about toxicity here is that the cells can take the particles in via either phagocytosis or endocytosis (two separate cellular mechanisms for taking in particles of various sorts). Once taken in things go into endosomes and these initial membrane bounded vesicles fuse with a lysosome forming a phagolysosome. In these vesicles things get digested by various enzymes.

Related QuestionsWhy attempt to isolate mumps virus in cell culture?
NIP: Diseases/Mumps/Mumps Lab Testing Q&AsVirus isolation is considered the best method to detect infection. Virus can be detected when IgM antibodies or IgG titer rise are not detected. Additionally, it provides virus that can be used for sequence studies. Finally, isolation studies are less likely than PCR assays to give false positive results because of contamination. The sequence of the PCR product will confirm positive PCR reactions.

Related QuestionsShould I use enrichment media to culture milk for mycoplasma?
Dairy Cattle Programs, UC Davis Veterinary Medicine Extensio...It all depends. Enrichment media has been shown to be useful when culturing individual cow milk samples. The recovery rate is much greater than that of the direct culture method. The lower limit of detection with enrichment is about 10 cfu and for direct plating it is about 100 cfu. The answer is not clear with bulk tank milk as there is no published research on this subject.

How can you replace the reactions of a whole animal in a test tube or a cell culture?
Dr Hadwen Trust: faqsNon-animal research rarely simply replaces like for like. Instead we use a different approach in order to replicate the whole body scenario, replacing each type of animal experiment with a whole range of non-animal techniques that are used in combination. When it comes to studying the “whole animal” it is wrong to assume that animals are the best choice, or that they are necessary to solve every medical problem.
