A linker-drug represented by formula (I) or a pharmaceutically acceptable salt or solvate thereof is provided. In formula (I), C is a conjugator, L is a linker unit, D is a toxin unit, and n is an integer ranging from 1 to 4. The structure of the conjugator is represented by formula (II). In formula (II), X is a leaving group, each of Rand Ris independently a single bond or &#x2014;NH&#x2014;, and Z is substituted aryl, heteroaryl, linear alkyl, cycloalkyl, heterocycloalkyl, or a combination thereof. The antibody is conjugated to the linker unit through a cysteine residue of the antibody. An antibody-drug conjugate (ADC) employing the above linker-drug is also provided. 

Linker-drug and antibody-drug conjugate (ADC) employing the same

A humanized monoclonal antibody against the CD34 surface antigen is provided in the present disclosure. The humanized monoclonal antibody includes a light chain variable region and a heavy chain variable region. In which, a nucleotide sequence encoding the amino acid sequence for the light chain variable region comprises a nucleotide sequence which encodes the amino acid sequence of SEQ ID No. 9 or an amino acid sequence with at least 80% sequence identity to the sequence of SEQ ID No. 9, and a nucleotide sequence encoding the amino acid sequence for the heavy chain variable region comprises a nucleotide sequence which encodes the amino acid sequence of SEQ ID No. 10 or an amino acid sequence with at least 80% sequence identity to the sequence of SEQ ID No. 10.

Humanized monoclonal antibody and uses thereof

A collagen scaffold domain, including a collagenous or collagen-like domain, which directs self-trimerization is provided. The collagen scaffold domain can be fused to one or more heterologous domains, such as an antibody domain. Methods for generating and using the scaffold domains and fusion proteins are also provided.
