The ATTO-TAG FQ Plus Amine Derivatization Kit was shipped on wet ice but the storage recommendation is at -20 degrees C? Is it still good to use?

Yes, the product is still good to use. We ship many of our products at a higher temperature than the storage recommendation. The product will be stable for at least one week at the shipping temperature when in the original, unopened packaging.

What is the difference between the ATTO-TAG FQ Plus Amine Derivatization Kit (Cat. No. A66521) and the ATTO-TAG FQ Amine-Derivatization Kit (Cat. No. A2334)?

The ATTO-TAG FQ Amine Derivatization Kit (Cat. No. A2334) contains a potassium cyanide (KCN) component (component B). This component has been removed in the ATTO-TAG FQ Plus Amine Derivatization Kit (Cat. No. A66521) and replaced with mandelonitrile which serves as a less toxic alternative to KCN without compromising assay performance.
