An efficient way to assist you in making the right choices: 1) You send us a description of your project/application by E-mail ( info(at)enzyscreen.com ), preferably with the following info: • What type of strain / cell line is being used • The type of product of interest (e.g. an enzyme, an anitibody, a secondary metabolite, etc) • The cultivation time (number of days) • The growth temperature • Your inoculation procedure • What the minimally required culture volume is • What minimal accuracy is required (maximal variability of independent duplicates) • The number of clones/mutants/conditions to be screened • The type of orbital shakers available in your lab (what trade mark, what shaking diameter) 2) We respond by E-mail or by phoning. Together, we establish what combinations of culture volume - microplate - sandwich cover - clamp system - shaking conditions is the most suitable for your purpose. 3) We supply you with a such a system which you test on a limited number of strains/mutants/cell lines, mainly to assess the reproducibility (standard deviation among independent duplicates), the productivity in comparison to your present cultivation systems (e.g. shake flasks or tubes). 4) In a phonecall, we together evaluate these initial tests, and decide which system to use for the full screenings Note: It is our experience (having worked in this way with already more than 100 customers) that it is worth to spend enough time on the optimization of the inoculation and screening procedure: it is often better to spend 8 weeks on optimization and 2 weeks on the screening itself than the other way around..
