The present invention relates to &#x3b5;-polylysine conjugates, in particular conjugates of &#x3b5;-polylysine with compounds carrying carboxyl groups, and to the preparation and use thereof for targeting of the kidney.

&#x3b5;-Polylysine conjugates and the use thereof

The present invention relates to a process for synthesizing biopolymers by stepwise assembly from protected synthesis building blocks which carry two-stage protective groups. The two-stage protective groups are activated by a first illumination step and eliminated by a subsequent chemical treatment step. Photoactivatable components which considerably speed up the activation process via intramolecular triplet sensitizers or/and have fluorescence properties are used. The two-stage protective groups can be used in particular within the framework of quality control.

Photoactivatable two-stage protective groups for the synthesis of biopolymers

The invention relates to a method for the synthesis of a nucleic acid by gradual breakdown from protected synthesis building blocks carrying two-stage protective groups. The two-stage protective groups are split by means of a first exposure step and a subsequent chemical treatment step
