Pouring gels for protein separation is a relatively archaic laboratory practice and is largely replaced by precast-protein gels. Academic, clinical, and pharmaceutical labs use precast gels to save time, simplify preparation, and obtain high-quality uniform results. Precast protein gels are available for isoelectric focusing (IEF), SDS-PAGE, and non-denatured protein analysis. Diverse protein separation requirements are met with the abounding types of precast gels on the market. The gel percentage, number of wells, size and thickness are evaluated prior to purchasing a box or boxes of gels. Gradient gels of 4-16% are ubiquitous choices, but single percentage gels of 2% or 10%, for example, are also available. Due to the myriad of providers, purchasing applicable precast gels is expedited by comparing the options listed on our online catalog.
