For cells, cell lines and tissues in culture till half confluency. A microtiter plate (spelled Microtiter is a registered trade name in the United States) or microplate or micro well plate or multiwell, is a flat plate with multiple "wells" used as small test tubes. The microplate has become a standard tool in analytical research and clinical diagnostic testing laboratories. A very common usage is in the enzyme-linked immunosorbent assay (ELISA), the basis of most modern medical diagnostic testing in humans and animals.
A microplate typically has 6, 24, 96, 384 or 1536 sample wells arranged in a 23 rectangular matrix. Some microplates have even been manufactured with 3456 or 9600 wells, and an "array tape" product has been developed that provides a continuous strip of microplates embossed on a flexible plastic tape. This 1 has passed a sterilization (or sterilization) by filtration or inactivation that has eliminated (removed) or killed (deactivated) all forms of DNA, RNA and enzymes. Also life and other biological agents (such as viruses which some do not consider to be alive but are biological pathogens nonetheless), excluding prions which cannot be killed, including transmissible agents (such as fungi, bacteria, viruses, prions, spore forms, unicellular eukaryotic organisms such as Plasmodium, etc.) present in a specified reagent or on a surface, a volume of fluid, or in a compound such as biological culture medias filtered. Sterilization was achieved with one or more of the following heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization in that sterilization kills, deactivates, or eliminates all forms of life and other biological agents.
