MultiScreen® microplates are available as non-sterile, 96-well and 384-well microplates in clear, white, black, or natural. Polystyrene microplates are commonly used for biochemical assays, including colorimetric, luminescent, and fluorescent applications (for example, Bradford-Lowry or luciferase assays) routinely performed on microplate readers. Polypropylene microplates are commonly used for storage of chemicals, nucleic acids, and proteins. These microplates can also be used for colorimetric assays and basic biochemical reactions.
Polystyrene is a highly clear polymer with excellent optical properties which makes it ideal for precise optical measurements. Polystyrene MultiScreen® Microplates are currently available as non-sterile, 96-well microplates in clear, white, or black.
Polypropylene is characterized by its excellent chemical and thermal stability. It is the ideal polymer for storage microplates. Polar molecules, such as proteins or DNA, bind less to polypropylene than to polystyrene. Polypropylene MultiScreen® Microplates are currently available as non-sterile microplates in natural 96-well and 384-well formats.
Enzyme-Linked Immunosorbent Assay (ELISA) is a plate-based assay technique designed for detecting and quantifying soluble substances such as peptides, proteins, antibodies, and hormones. MultiScreen® ELISA Microplates are made of polystyrene and available in 96-well or 8-well strip formats. 8-well strip formats allow for single columns “strips” of wells to be used in an assay rather than consuming the entire microplate. These are available with medium or high binding surfaces to best suit the needs of the application and molecules involved.
