Abstract

Apparatus and methods utilizing induction-heat energy for heating reactions associated with chemical synthesis, such as peptide synthesis reactions involving activation, deprotection, coupling, and cleavage. Thorough agitation of the contents of reaction vessels during heating, real-time monitoring and adjustment of temperature and/or reaction duration, independent control of different reaction vessels, and scalability are also described.

Claims (39)

1. A chemical synthesis reaction-heating platform, comprising:

one or more reaction vessels, and

a source of induction-heat energy configured to heat a content of said one or more reaction vessels,

wherein said one or more reaction vessels is coated with a heat-conductive material that comprises a plurality of layers of a metal conductor paste, and

wherein said platform is configured to shake or mix said content in the one or more reaction vessels during a process of heating said content.

2. The platform of claim 1 , wherein said platform is configured to shake or mix through motion said one or more reaction vessels during heating in a manner such that said one or more reaction vessels are free from contact with said source of induction-heat energy.

3. The platform of claim 1 , wherein said heat-conductive material comprises three to five layers of DUPONT 7713 conductor paste baked onto said one or more reaction vessels.

4. The platform of claim 1 , wherein said platform further includes an infrared (IR) heat temperature sensor and said one or more reaction vessels is configured to diffuse and homogenize IR radiation.

5. The platform of claim 4 , wherein said one or more reaction vessels contains a surface dimensioned to diffuse and homogenized IR radiation.

6. The platform of claim 1 , further including a controller configured to control temperatures of more than one reaction vessels independently.

7. The platform of claim 1 , further including independent controllers and power amplifiers configured to control temperatures of one or more selected reaction vessels.

8. The platform of claim 1 , wherein induction source of induction-heat energy comprises a free-floating induction coil, said induction coil and associated reaction vessel being configured such that each moves synchronously to thereby maintain desired field alignment and distance parameter.

9. An instrument for solid phase peptide synthesis, comprising:

one or more reaction vessels, and

a source of induction-heat energy configured to heat a content of said one or more reaction vessels,

and

means for actuating and controlling fluid transfers and heating necessary for peptide synthesis;

wherein said one or more reaction vessels is coated with a heat-conductive material that contains a plurality of layer of a metal conductor paste, and

wherein said instrument is configured to shake or mix said content of the one or more reaction vessels during a process of heating of said content.

10. The instrument of claim 9 , wherein said platform is configured to shake or mix through motion said one or more reaction vessels during said process of heating in a manner such that said one or more reaction vessels are free from contact with said source of induction-heat energy.

11. The instrument of claim 9 , wherein said heat-conductive material comprises three to five layers of DUPONT 7713 conductor paste baked onto said one or more reaction vessels.

12. The instrument of claim 9 , wherein said platform further includes an infrared (IR) heat temperature sensor and said one or more reaction vessels is configured to diffuse and homogenize IR radiation.

13. The instrument of claim 12 , wherein said one or more reaction vessels contains a surface dimensioned to diffuse and homogenized IR radiation.

14. The instrument of claim 9 , further including a controller configured to control temperatures of more than one reaction vessels independently.

15. The instrument of claim 9 , further including independent controllers and power amplifiers configured to control temperatures of one or more selected reaction vessels.

16. The instrument of claim 9 , wherein said source of induction-heat energy comprises a free-floating induction coil, said induction coil and associated reaction vessel being configured such that each moves synchronously to thereby maintain desired field alignment and distance parameter.

17. The instrument of claim 13 , wherein said one or more reaction vessels includes a bottom with an opening that is dimensioned to transfer a fluid from said one or more reaction vessels.

18. An instrument for solid phase peptide synthesis, comprising:

one or more reaction vessels, and

a source of induction-heat energy configured to heat contents of said one or more reaction vessels,

wherein said one or more reaction vessels is coated with a heat-conductive material,

means for actuating and controlling fluid transfers and heating necessary for peptide synthesis,

and

an infrared (IR) heat temperature sensor,

wherein said one or more reaction vessels is configured to diffuse and homogenize IR radiation,

and

wherein said instrument is configured to shake or mix said contents of the one or more reaction vessels during a process of heating of said contents.

19. The instrument of claim 18 , wherein said heat-conductive material comprises a plurality of layers of metal conductor paste.

20. The instrument of claim 18 , including a controller configured to control temperatures of more than one from said one or more reaction vessels independently.
