Product Specification Source/Host: Conjugated to agarose. Long Term Storage: +4°C Miscellaneous/General: UQ1-UBA efficiently captures mono-ubiquitin and ubiquitin conjugates including free chains in a linkage independent manner. It has been demonstrated that UBA sequence motifs may retain their function in isolated form and consequently many find utility in the isolation and characterization of multi-ubiquitinylated species.
