The pan-Ubiquitin Remnant Motif (K-epsilon-GG) Antibody (CAB20303) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, raised in rabbits, specifically targets the K-GG motif present in ubiquitin remnants, allowing for precise detection and analysis in various biological samples.Ubiquitination is a post-translational modification crucial for protein turnover, DNA repair, and signal transduction pathways. Dysregulation of the ubiquitin system has been linked to various diseases, including cancer, neurodegenerative disorders, and inflammatory conditions.
This antibody is validated for use in WB, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.

Ubiquitination plays a key role in protein degradation and signal transduction. Characterization of ubiquitination sites is important for understanding the role of this modification in cellular processes and disease. Ubiquitination sites are usually identified by detection of Lys-?-Gly-Gly (K-?-GG)-remnant peptides, which are generated by tryptic digestion of proteomes. The di-glycine remnant left at sites of ubiquitination after trypsin digestion through cleavage of the C-terminal –RGG sequence on ubiquitin (K-ε-GG). This Ubiquitin K-ε-GG remnant motif antibody will recognize the di-glycine remnant independent of flanking amino acid sequence.
