Certificate of Analysis

Certificate of Origin

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What do you recommend to use as a negative control for Product C9210, Cyanogen bromide?

    The control for this product is Product No. CL4B200 (Sepharose CL-4B).

  4. What is the difference between Product C9210, Cyanogen bromide and Product C9142, Cyanogen bromide-activated-Sepharose® 4B?

    Sigma-Aldrich produces product C9210, while C9142 is produced by GE Healthcare.  In addition, C9210 is a cross-linked resin and C9142 is not.

  5. When using Product C9210, Cyanogen bromide, why must amine containing reagents be avoided during coupling?

    The ligand is attached to the resin via an amine group. If an amine-containing buffer is used during coupling, you will greatly reduce the amount of ligand that can attach.

We developed fluorescent biosensor systems that are either general or selective to fluoroquinolone antibiotics by using a single-chain variable-fragment (scFv) as a recognition element. The selectivity of these biosensors to fluoroquinolone antibiotics was rationally tuned through the structural modification on...
