AF430 is a fluorescent dye. AF430 has an excitation maximum at 430 nm and an emission maximum at 542 nm. AF430 is one of the few dyes that absorb between 400 nm and 450 nm. AF430 fluorescence is photostable and pH-insensitive in a broad range of pH values.

Tetrazine residue participates in the fast copper-free click reaction that is well suited to non-toxic in vitro cell labeling and low-concentration applications.

AF430 是一种荧光染料。 AF430 在 430 nm 处具有最大激发,在 542 nm 处具有最大发射。 AF430 是为数不多的在 400 nm 和 450 nm 之间吸收的染料之一。 AF430 荧光在广泛的 pH 值范围内具有光稳定性和 pH 不敏感性。
