text: Thermoresponsive conjugates have been exploited for the subsequent separation of proteins from a complex mixture. This method has been utilized to purify polyclonal antibodies in serum samples. This method of purification is rapid, sensitive, inexpensive and could be used to purify various types of antibodies.
  Thermoresponsive conjugates can also be exploited to mediate bioactivity. One of the utilities of the method is demonstrated temperature control of biotin binding and release. Biotin binding was observed below the LCST, while above the LCST the conjugates aggregated, and the biotin binding affinity was reduced by ~20%. By changing the temperature, the recovery of the biotinylated molecules can be achieved.
