July 31, 2014, Lincoln, NE: LI-COR’s newest product family, the Chameleon™ Pre-stained Protein Ladders, offers the unique advantage of multi-colored visible and 2-color near infrared (NIR) fluorescence detection in a single ladder. Each product provides an array of sharp and distinctive bands of recombinant proteins for molecular weight determination in a broad size range.
Chameleon products are optimized for use with Odyssey® Infrared Imaging Systems.
"This first-of-its-kind technology with matching multi-color visible and NIR bands, will simplify determination of protein size, gel migration, and membrane orientation," says Shawn Mischnick, technical product manager at LI-COR Biosciences. "The Chameleon product family will provide customers with a versatile solution to best suit their NIR Western blotting needs," she adds.
The Chameleon family is comprised of four products. The Chameleon Duo Pre-stained Protein Ladder resolves into 11 bands of orange, blue or green, ranging from 8 to 260 kDa upon electrophoresis, and is an ideal size standard for dual-channel (700 nm and 800 nm) NIR detection. The Chameleon 700 Pre-stained Protein Ladder separates into 7 multi-colored bands, and can be detected in the 700 nm NIR channel. Similarly, the Chameleon 800 Pre-stained Protein Ladder yields 6 corresponding bands for visual and 800 nm NIR detection. The Chameleon Kit, consisting of a vial each of Chameleon 700 and Chameleon 800, enables customization of protein ladder intensity in each channel, and offers detection capabilities of Chameleon Duo when the components are combined.
