Abstract
The disclosure provides for methods and apparatuses relating to technology for monitoring chemical and/or biological reactions. Some methods provided herein relate to utilization of NAPPA technology to create large protein arrays suitable for use in combination with various ISFET arrays to enable massive parallel assays of kinase activity and inhibition. Some devices provided herein relate to CMOS chips which utilize the NAPPA array technology to build protein inventories of interest upon an ISFET architecture. Further devices provided herein are capable, inter alia, of processing the arrays created by the combination of NAPPA technology and ISFET architecture.
Claims5
A method for evaluating phosphorylation of an array of proteins, comprising:
- 1) exposing an ion-sensitive field effect transistor (ISFET) to a protein phosphorylation reaction;
- and
- 2) detecting an electrical signal output from said ISFET;
- wherein the ISFET is integrated into a complementary metal-oxide semiconductor (CMOS);
- wherein a CMOS surface is coated with a chloroalkane compound;
- and
- wherein at least one protein comprising a protein tag involved in the protein phosphorylation reaction is deposited onto the CMOS surface by using nucleic-acid programmable protein array (NAPPA) technology.
