Source:
Human QR2 was expressed and purified from E. coli cells.
Prep. Method:
The enzyme was further applied to a Hiload 26/60 Superdex 75 (GE Healthcare) column. The fractions containing pure enzyme were pooled and finally applied to a 10/100 GL MonoQ (GE Healthcare) strong anion-exchange column. The protein was eluted using a gradient. The purest protein fractions were pooled, buffer-exchanged and concentrated. Samples of QR2 were extensively dialysed against ITC buffer, and degassed before assay.
