The invention relates to a method for identifying the function of a ligand L using chromophore-assisted laser inactivation (CALI), characterized by the stages:
a) selecting a ligand binding partner (LBP) with specificity for the ligand L,
b) coupling the LBP to a laser-activatable marker (tag) to form LBP-tag, where appropriate after previous modification of the LBP with the aim of more efficient binding to the marker,
c) bringing the ligand L into contact with at least one LBP-tag to form an L/LBP-tag complex, and
d) irradiating the L/LBP-tag complex with a laser beam, whereupon the irradiated LBP-tag selectively modifies the bound ligand, it being possible to interchange the sequence of stages b) and c).
The invention also relates to an apparatus for carrying out the method according to the invention.
本发明涉及一种利用发色团辅助激光灭活(CALI)鉴定
配体 L 功能的方法,其特征在于以下阶段:
a) 选择对
配体 L 具有特异性的
配体结合伙伴(LBP)、
b) 将 LBP 与可激光激活的标记(标签)耦合,形成 LBP-标签,在适当的情况下,事先对 LBP 进行修饰,以便更有效地与标记结合、
c) 使
配体 L 与至少一个枸杞
多糖标记接触,形成 L/LBP-tag 复合物,以及
d) 用激光束照射 L/LBP-tag 复合物,此时被照射的 LBP-tag 选择性地改变结合的
配体,b)和 c)阶段的顺序可以互换。
