The ULS Protein Labeling and Detection Kits are based on KREATECH’s Universal Linkage System (ULS). The kits provide an easy and reproducible method for labeling proteins from serum, plasma and cell lysates, as well as detection of analytes on antibody arrays. Kits are available in both dual and single color format and are compatible with many array surfaces and commercial array platforms.
Unique features of the Protein Labeling and Detection Kits
- All reagents provided in one kit.
- Available as single or two color kits
- ULS-Trap purification columns - removes all unreacted ULS label
- Provides high coverage (>98%) of the proteome through specific labeling of methione, cysteine, and histidine residues.
Dual color Cell lysate incubated on Clontech antibody array slide.

Dual color Serum incubated on nitrocellulose-based antibody array.

Single-color Cell Lysate with fluorescent labeling.
