Abstract
A method of producing an antibody fragment for a target antigen includes administering an immunizing mixture containing the target antigen to a cartilaginous fish for at least two times; collecting a blood sample from the cartilaginous fish; extracting RNAs from the blood sample; subjecting said RNAs to reverse transcription to obtain a complementary DNA, and optionally amplifying the cDNA to obtain a mixture of amplified cDNAs followed by purification. Also covered are methods of producing an antibody fragment from a shark; antibody fragments obtained from the method; a kit comprising antibody fragments; and methods of determining the presence and/or amount of a target antigen in a sample.
