3 个常见问题解答

Is there a cleavable analog of Sulfo-NHS-LC-Biotin?

Yes, we offer Sulfo-NHS-SS-Biotin (Cat. Nos. 21331, 21328). It has a disulfide bond in the spacer arm that can be cleaved with DTT or other reducing agents, thereby releasing the biotin tag from the previously labeled protein. This product is also available in kit format (Cat. Nos. 21945, 21445).

How do the EZ-Link Micro Biotinylation Kits differ from the standard biotinylation kits?

The standard biotinylation kits contain components for labeling 1-10 mg of protein, and the Micro Biotinylation Kits are structured for labeling 50-200 µg of protein in 200-700 mL. The Micro kits contain the biotinylation reagents in small, individual packages and do not include components to perform the HABA assay.
