b'Overview of precast gelsInvitrogen precast gels offer convenience, speed, and consistency. We offer precast gels in four different formulations and a wide variety of percentages, gradients, and sample well configurations. The choice of whether to use one formulation or another depends on the abundance of the protein you are separating, the size of the protein, and your downstream application.Four gel options to fit your protein separation needs:Bis-Tris gels for broad-range, low-abundance protein separation, or for downstream applications requiring high protein integrity, such as posttranslational modification analysis, mass spectrometry, or sequencingTris-glycine gels for broad-range, high-abundance protein separation Tris-acetate gels for high molecular weight protein separation, up to 500 kDaTricine gels for low molecular weight protein and peptide separationFind out more at thermofisher.com/proteingelsProtein gel performance guaranteeWe stand behind the quality of our high-performance protein gels. Purchase Invitrogen protein gels with confidence, knowing that our gels are backed by our protein gel performance guarantee. If an Invitrogen protein gel does not perform in your experiment as described on our website or Certificate of Analysis, we will replace the product at no cost to you, or we will provide you with a credit for future purchase.Learn more at thermofisher.com/proteingelguaranteeProtein gel welcome packsInvitrogen protein gel welcome packs contain the components for outstanding protein separation and are available for mini- and midi-format protein gels. The typical protein gel welcome pack provides all of the necessary gels, buffers, and reagents you need, as well as an Invitrogen Mini Gel Tank, Invitrogen XCell SureLock Mini-Cell, or Invitrogen SureLock Tandem Midi Gel Tank. Protein gel welcome packs are also available in mini gel and midi gel formats designed for use in protein expression experiments and subsequent purification steps.Find out more at thermofisher.com/proteingelwelcomeProtein gel electrophoresis thermofisher.com/proteinbiology 43'
