常见问题解答 (FAQ)

I'm using an Amplex Red kit, the reagent changes color to pink almost immediately in my own Krebs-Ringer buffer but not in HBSS. Why is this?

The components of Krebs-Ringer buffer (salts) should not cause oxidation of the Amplex reagent (which, in the presence of peroxidase and H2O2 oxidizes to resorufin, which is pink in color and fluorescent). Try water alone (the water used to make the Krebs-Ringer buffer). Since Hank's Buffered Saline Solution is typically purchased rather than made in the lab, it likely would not have the same contaminant. Another option is to degas the buffer prior to use to removed dissolved oxygen radicals.

Can Amplex Red Assays be performed using cell lysates?

This is not recommended. The presence of endogenous proteases can complicate the assay by degrading the horseradish peroxidase (HRP). Endogenous peroxidases and antioxidants can modify the H2O2 required for the reaction, competing with HRP (and catalase) for the substrate.

The Amplex Red Assays are best performed with either purified enzymes or extracted H2O2 in a defined buffer system, extracellular solutions or body fluids (media, serum, etc.) that do not exhibit high levels of endogenous protease or oxidase activity and do not contain antioxidants.

'Cell survival signaling is important for the malignant phenotypes of cancer cells. Although the role of receptor-interacting protein 1 (RIP1) in cell survival signaling is well documented, whether RIP1 is directly involved in cancer development has never been studied. In this report, we found that RIP1 expression is substantially increased ... More
