This invention relates to the field of biopharmaceutical manufacturing technology, and discloses a BCMA-targeting nanobody, its preparation method, and its application. The nanobody comprises a heavy chain single-domain binding domain, a helical conformation-constrained peptide chain, and an amphiphilic self-assembled polypeptide sequence. The helical conformation-constrained peptide chain forms a steric barrier between the binding domain and the polypeptide sequence through physical length, maintaining the monomeric conformation of the polypeptide sequence in a free state. When the binding domain is anchored at the receptor binding interface, the conformation-constrained peptide chain increases the local effective concentration of the polypeptide sequence within the confined space, inducing intermolecular topological assembly. This invention utilizes a kinetic phase transition mechanism to generate a binding state jump, maintaining the conformational activity of the composition in the circulatory system, reducing off-target toxicity, and prolonging the residence time at the receptor interface.

Materials, methods, means, steps and systems for determining occupancy of a multi-target agent at two or more targets in the same cell. The method generally includes use of multiple detection reagents to determine a bound condition of the multi-target agent to each of the multiple targets, respectively. Each detection reagent includes a detectable label and is designed to bind a specific region of the multi-target agent unique to the agent's ability to bind to one of the multiple targets on the cell surface, thus providing single bound signals. A total amount of the multi-target agent bound to the multiple targets is determined using a universal detection reagent designed to bind to a common region of the multi-target agent. Subtracting specific single bound signals from bound signals allows calculation of multiply bound signals and specific total signals. This approach allows for the measurement of target occupancy for each bound condition with each target.
