HRP Plate Assay and Colony PCR
| Question | Answer |
|---|---|
| methanol | turns on alcohol oxidase promoter which is attached to HRP protein expression and mat alpha secretion sequence |
| what does HRP do? (HRP plate assay test) | it is an enzyme that converts substrate TMB to blue product |
| PCR test | use oligonucleotide primers that hybridize within HRP gene to amplify a portion of HRP from colony. if you get a PCR product of expected size, it is a stud. if not, it is a dud. |
