CDK5 底物 PKTPKKAKKL（5-TMR 标记）：含磷酸化基序与 TAMRA 荧光团，用于可视化，碱性残基支持激酶相互作用，标记物实现实时监测，可用于激酶 - 底物谱分析、结构研究与磷酸化定位。

CDK5 Substrate PKTPKKAKKL, 5-TMR labeled incorporates a phosphorylation motif coupled to a TAMRA fluorophore for visualization. The basic residues support kinase interaction, while the label enables real-time monitoring. Researchers employ it in kinase-substrate profiling, structural studies, and phosphorylation mapping.

TAMRA标记的说明:

Single isomer 5-Carboxytetramethyl rhodamine (5TAMRA) and mixed-isomer 5/6-TAMRA are fluorophors with excitations at ~543 nm ▉ and emissions of ~572 nm ▉.
