Polymer Laboratories (PL), now a part of Varian, Inc., manufactures a range of custom microparticle products in the size range 2-25µm for use in life science and bioscience applications.
Particles are available with a range of surface functionalities, including: -CHO, -COOH and streptavidin-coated.
PL-MicroSpheres are also available in a range of HiDyeTM colors, which offer all the features of the white particles with the added advantage of intense color. As the dye is not surface bound, it does not interfere with the binding of the ligand.PL's intensely-colored HiDyeTM particles PL's innovative research into highly-dyed colored particles played a primary role in assisting diagnostic companies in the development of the first membrane capture and migration assays, in the adoption of a color-coded identification system for diagnostic test reagents and cell labelling studies.
Applications include immunoassay formats, cell labelling studies, flow cytometry and for use as cell analogs.
