Engineering For Expression Of The Cold Regulated Barley Protein Hvcr21 In E. Coli, Kathleen Graupman
The Journal of Undergraduate Research
HVCR21 is a barley protein known to be cold regulated at the mRNA level. However, its function as well as the affect of low temperature on its translation are unknown. The purpose of this project was to engineer E. coli to express recombinant HVCR21. PGR primers were designed for the 5' and 3' ends of the HVCR21 coding region. The primers were also designed with a 5' SacI restriction site and a 3' Pst I restriction site. After ligation of the PCR product into the pCR4-TOPO vector, bacteria were transformed and plated and the successful transformant verified by PCR. The …
