However‚ these conditions are not sufficiently representative of the complex in vivo environment‚ and encourage cells to behave differently than they would in the host organism. This discrepancy results in misleading data. • Often‚ experimentation on cells cultured in standard static 2D conditions is not sufficient to meet research

Figure 1. In vivo C3 binding on red cells of PNH patients on eculizumab. (A) Kinetics of C3 binding on red cells from a representative PNH patient during eculizumab treatment. Before treatment (0 wks) no red cell binds C3‚ whereas starting from 1 weeks of treatment three populations of red cells are displayed: one population of normal red cells (CD59+C3-) and two distinct populations of PNH (CD59-negative) red cells‚ one with (C3+) and one without (C3-) fragments bound on their surface.

individual is different it will lead to different reactions depending on the individual. Therefore‚ is extremely important not to generalize and treat each case individually. Lastly another way CPPS are limited is that although not a factor in vitro‚ in vivo application certain enzymes present in the cells can denature the peptides. Currently there is limited research that has been done in humans but in theory this could be a huge breakthrough in the field. Moreover‚ what many of these initial studies

of each species‚ depending on the degree to which the toxic plants were present in their microhabitat. The brush-tailed possum (T. vulpecula) from Western Australia was found to be nearly 150 times more resistant to fluoroacetate intoxication in vivo than the same species from South Australia. Both possums are capable of de-fluorinating fluoroacetate at similar rates by a glutathione-dependent enzymic mechanism resulting in the formation of free fluoride ion and S-carboxymethylcysteine.

In the absence of any in vivo or clinical studies however‚ it is not clear if this antimicrobial activity has any therapeutic relevance.

experiments so painful and damaging that no one would ever do on any human being. As experimenting on animals is immoral we should stop using animals for experiments. Animal experimentation‚ also known as animal testing‚ animal research‚ and in vivo testing is the use of non-human animals in experiments. Animal testing is very cruel. Animals are kept in boxes or cages that they can barely move in. They are tested to what substance cause pain‚ stress or even both. Animal testing kills about 50

If that is true‚ then why is Vitro testing growing in popularity? Vitro testing could completely replace animals use in testing. Vitro testing is all done in a test tube. According to Bonnie of being animal experimentation ethical "As opposed to in vivo‚ in the living being test‚ in a vitro test are performed in test tubes‚..."( Is Animal Experimentation ethical 69). If testing in test tubes‚ and not in living beings‚ the need for animals will drop. Using test tube will not only drop animal use‚ it
