|Predicted MW||104.1 kDa|
|Purity||>90% by SDS PAGE|
|Buffer||Presentation State: Purified
State: Liquid purified protein
Buffer System: 20 mM Tris-HCl pH 8.0, 10% glycerol
|Bioactivity||Specific: 3-4 units/ml obtained by measuring the increase of NADPH in absorbance at 340 nm resulting from the reduction of NADP. In the coupled mode, one unit will produce 1.0 umole of NADPH per minute as glucose is phosphorylated by ATP at pH 7.4 at 30°C.|
|Preparation||Liquid purified protein|
|Applications||Protocol: Activity Assay
1. Prepare a 2.57 ml reaction mixture into a suitable container: The final concentrations are 39mM triethanolamine, 216 mM D-glucose, 0.74mM ATP, 7.8 mM MgCl2, 1.1 mM beta-NADP, 2.5 units G6PD.
2. Equilibrate to 25°C and monitor the A340nm until the value is constant using a spectrophotometer.
3. Add 5ug of recombinant hexokinase2 into reaction mixture and mix immediately.
4. Record the increase in A340nm for 5 minutes.
|Protein Description||Recombinant human Hexokinase 2, fused to His tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.|
|Storage||Store undiluted at 2-8°C for up to two weeks or (in aliquots) at -20°C or -70°C for longer.
Avoid repeated freezing and thawing.
|Stability||Shelf life: one year from despatch.|
|Summary||Hexokinases phosphorylate glucose to produce glucose-6-phosphate, the first step in most glucose metabolism pathways. This gene encodes hexokinase 2, the predominant form found in skeletal muscle. It localizes to the outer membrane of mitochondria. Expression of this gene is insulin-responsive, and studies in rat suggest that it is involved in the increased rate of glycolysis seen in rapidly growing cancer cells. [provided by RefSeq, Apr 2009]|
