K48-linkage Specific Ubiquitin Monoclonal Antibody (CAB3606)
The K48-linkage Specific Ubiquitin Monoclonal Antibody (CAB3606) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, produced in rabbits, is highly specific and sensitive for detecting K48-linked ubiquitin in human samples. Ubiquitination is a crucial post-translational modification involved in regulating protein degradation, cell signaling, and various cellular processes. K48-linked ubiquitin chains, in particular, target proteins for proteasomal degradation. The CAB3606 antibody recognizes these specific ubiquitin chains, allowing researchers to study their role in various biological pathways.This antibody is validated for use in Western blot applications, enabling researchers to detect and quantify K48-linked ubiquitin conjugates in different cell types and experimental conditions.
This antibody is validated for use in WB, IF/ICC, ELISA applications and has demonstrated reactivity against Human samples.

This gene encodes ubiquitin, one of the most conserved proteins known. Ubiquitin has a major role in targeting cellular proteins for degradation by the 26S proteosome. It is also involved in the maintenance of chromatin structure, the regulation of gene expression, and the stress response. Ubiquitin is synthesized as a precursor protein consisting of either polyubiquitin chains or a single ubiquitin moiety fused to an unrelated protein. This gene consists of three direct repeats of the ubiquitin coding sequence with no spacer sequence. Consequently, the protein is expressed as a polyubiquitin precursor with a final amino acid after the last repeat. An aberrant form of this protein has been detected in patients with Alzheimer's disease and Down syndrome. Pseudogenes of this gene are located on chromosomes 1, 2, 13, and 17. Alternative splicing results in multiple transcript variants.
