Basic research includes studies of a fundamental nature including physiology. Studies that are designed to add knowledge about normal and abnormal structure, functioning and behaviour of living organisms and environment, this includes fundamental studies in toxicology. Investigation and analysis focused on a better or fuller understanding of a subject, phenomenon, or a basic law of nature instead of on a specific practical application of the results.
The animals used for the creation of a new genetically altered animal line (including crossing of two lines) intended to be used for the purposes of basic research (e.g. developmental biology, immunology) should be recorded according to the purpose they are being created for. In addition they should be reported in "Creation of a new genetic line – Animals used for the creation of a new genetically altered line/strain".
All animals carrying the genetic alteration should be reported during the creation of a new line. Also animals used in creation, such as for superovulation, vasectomy and embryo implantation, are reported here. The reporting should exclude non-genetically altered (wild type) offspring.
A new strain or line of genetically altered animals is considered to be "established" when transmission of the genetic alteration is stable, which will be a minimum of two generations, and a welfare assessment has been completed.
