DCVJ (9-(2,2-Dicyanovinyl)julolidine) 是一种分子转子和独特的荧光染料，与微管蛋白和肌动蛋白结合，聚合后荧光强度显著增加。DCVJ 还与磷脂双层结合并增加其荧光强度。DCVJ 可以检测肥大细胞脱颗粒的动力学过程。

β-Amyloid (7-22)

Inhibitor of protein kinase C (PKC) ζ; attached to cell permeabilisation Antennapedia domain vector peptide. Consists of amino acids 113 - 129 of PKC ζ pseudosubstrate domain linked by a disulphide bridge to the Antennapedia domain vector peptide. The Antennapedia peptide is actively taken up by intact cells, at 4 or 37°C, ensuring rapid and effective uptake of the inhibitor peptide. Once inside the cell, the disulphide bonds are subjected to reduction in the cytoplasm leading to release of the inhibitor peptide. Induces mast cell degranulation by a PKC ζ-independent pathway.
