Recommend reconstitute recombinant proteinase K powder in sterile water or 20mM Tris-HCl (pH 7.4~8.0), 1mM CaCl2, 50% glycerol at 20mg/ml. Further dilutions can be made in another aqueous buffer.
The activity of recombinant proteinase K is tested by hemoglobin, and one unit is defined as the amount of enzyme that will hydrolyze urea-denatured hemoglobin to produce color equivalent to 1.0 µmol tyrosine per min at 37°C, pH 7.5.
Yes, it is.
We detect DNase with λ-DNA electrophoresis method and detect RNase with RT-PCR.
The concentration of recombinant proteinase K solution is 20mg/mL, and calcium and glycerin are added as protective agents.
The price depends on demand quantity and order times. But we can provide gradient quotation sheet like 10g, 50g and 100g. Price details can be negotiated.
The capacity of recombinant proteinase K is about 80kg per month.
No, we do not. If customers have any requirement, we could do it.
The recombinant proteinase K is recommended stored at temperature 2-8°C for at least 24 months. We do not recommend to store it at room temperature.
