Skin and connective tissue disorders are a group of diseases that affect the skin, muscles, bones, blood vessels and other connecting tissues. These diseases may be caused by genetics, immune abnormalities, environmental factors, or other unknown factors. Some common skin and connective tissue diseases include systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), dermatomyositis, dry syndrome (SS), and systemic sclerosis.
In recent years, progress is being made in drug development for skin and connective tissue diseases, some of which are listed below:

Measured by its binding ability in a functional ELISA. Immobilized HER2 at 2 μg/ml can bind Trastuzumab, the EC50 is 2.179-2.825 ng/ml.

Measured by its binding ability in a functional ELISA. Immobilized PD-1 at 2 μg/ml can bind Anti-PD-1 recombinant antibody, the EC50 of human PD-1 protein is 6.087-7.854 ng/ml.

Measured by its binding ability in a functional ELISA. Immobilized human CD20 at 2 μg/ml can bind Anti-CD20 recombinant antibody (CSB-RA015007A1HU), the EC50 is 3.243-7.085 ng/mL
