Description
Biotin-N-terminal Ubiquitin
human recombinant
Product Information
50 μg
Soluble in aqueous buffers up to 20 mg/ml.
8.6 kDa
> 95% by PAGE
This is a lyophilized powder
Use & Storage
Depending on desired signal strength and assay conditions, biotin-N-term Ub should be used in conjunction with native ubiquitin at combined concentration range of 10-50 μM with a 1:2 to 1:20 ratio of biotin-N-term Ub: native Ub, respectively. Typical amounts for a 20 μL reaction: 250 ng to 2 μg biotin-Nterm- Ub, 5 μg native ubiquitin. Poly-ubiquitin chain visualization/quantitation can be performed via avidin-linked detection.
Store at -20°C once reconstituted. Avoid multiple freeze/ thaw cycles.
Catalog #: UB-560
Biotin-N-terminal Ubiquitin
Product Source:
human recombinant
Produced via a proprietary process resulting in a single biotin modification exclusively on the Nterminus of ubiquitin. This site-specific modification results in an ubiquitin that is fully functional at the C-terminus, and with the full compliment of reactive lysines to allow for polyubiquitin chain incorporation. Detection with avidin-linked reagents allows for a higher efficiency and detection sensitivity than with anti-ubiquitin antibodies. Ideal as an alternative to radio-labeled ubiquitin.
