Protein Electrophoresis
In Vitro Technologies has partnered with Protein Ark to bring you their latest Electrophoresis range.
- Rapid staining – Protein bands appear after minutes – Fully stained after 1 hour
- Highly sensitive – 5 ng bands resolved
- Accurate protein quantification – Low background – Linear staining range
- Re-useable – Up to 3 times
- Storage – 1 year at room temperature
The Elite Pre-stained Protein Ladder is designed for SDS polyacrylamide gel electrophoresis (PAGE) and Western blotting. The ladder is comprised of highly purified recombinant proteins to produce sharp bands.
The perfect pair for rapid and most economical SDS-PAGE
• Quicker results with rapid protein stain that gives bands in minutes
• Great value as stain can be re-used up to 3 times
• Easy to use with a simple single step procedure

Elite Pre-stained Protein Ladder
• Half your cost with only 2µl of protein ladder
• Easily determine MW with ultra-clear and expanded MW range (6.5-270kDa)
• Perfect for western blotting with up to 100%electro-transfer efficiency* and LI-COR® system compatibility

“Protein Ark Elite pre-stained protein ladder transfers much better and brighter at half the volume”
“Quick Coomassie clearly out performs our standard stain (Instant Blue) on speed, showing clearly defined bands after 1 minute and fully staining the gel after only 1 hour
(Instant blue took 3 hours to fully stain a duplicate gel) … I am converted!”
Introducing: Protein Ark Elite Agarose Tablets
Convenient, Ready-to-Use Agarose tablets.
Protein Ark Elite Agarose Tablets contain everything necessary for an easy preparation of an agarose gel in desired gel percentage. Ideal for routine DNA and RNA gel electrophoresis and blotting assays.
• Prepare your gel in minutes, all you need is water (3-in-1 tablets) or running buffer (2-in-1 and agarose tablets)
• Ready-to-Use tablet format: No messy weighing and improved gel-to-gel reproducibility
• 3-in-1 tablets pre-formulated with Ultrapure Agarose, Magnite Green DNA stain and either TBE or TAE buffer
• 2-in-1 tablets pre-formulated with Ultrapure Agarose and Magnite Green DNA stain
• Magnite Green DNA stain*: safer, non-carcinogenic alternative to Ethidium Bromide. Emits green fluorescence when bound to ssDNA, dsDNA and RNA.
*Excitation peak: ~490 nm. Emission wavelength: ~530 nm
