Provided herein are methods for making targeted therapeutics. In several embodiments, the therapeutics are directed against soluble agents such as toxins, venoms, and/or other factors that alter physiological biopathways as well as methods of using such therapeutics to treat patients or patient populations to reduce, eliminate, or inactivate, detrimental soluble agents that such patients or patient populations have been exposed to. In several embodiments, the therapeutics are directed to patient-specific disease markers. In several embodiments, the methods comprise screening a library comprising proteins linked to their cognate mRNAs to identify mRNA-protein pairs that bind to the diseased cells, isolating one or more proteins from the identified mRNA-protein pairs, and conjugating the isolated protein(s) to a therapeutic agent.

Immunochromatography test strip for detecting pollution of diacetoxyscirpenol, preparation method therefor, and application thereof
