Product Overview

Online Datasheet in PDF
Product Name
KspAI, Restriction Enzyme
Full Product Name
KspAI (HpaI)
Purity/Purification
Molecular Biology Grade
Preparation and Storage
-20 degree C
Dilution Buffer
10mM Tris-HCl (pH 7.4 at 25 degree C), 100mM KCl, 1mM EDTA, 1mM DTT, 0.2mg/ml BSA and 50% glycerol, or Storage Buffer.
Digestion of Agarose-embedded DNA
A minimum of 5 units of enzyme is required for digestion of 1ug of agarose-embedded lambda DNA in 16 hours.
Methylation Effects
The hemi-methylated sequence GTTAAm5C is cleaved by KspAI at a significantly slower rate. Cleavage is blocked when both strands are methylated as shown: 5'…GTTAAm5C…3' 3'…m5CAATTG…5'. Overlapping CG methylation may influence DNA cleavage. KspAI does not cut GTTm6AC. Blocked by overlapping EcoKI methylation.
Labeled Oligonucleotide (LO) Assay
No detectable degradation of a single-stranded and double-stranded labeled oligonucleotide was observed after incubation with 10 units of restriction endonuclease for 4 hours.
Ligation/Recutting Assay
After 50-fold overdigestion (3u/ug DNA x 17 hours) with KspAI, more than 90% of the DNA fragments can be ligated at a 5'-termini concentration of 0.14uM. More than 90% of these can be recut.
Overdigestion Assay
No detectable change in the specific fragmentation pattern is observed after 80-fold overdigestion (5u/ug lambda DNA x 16 hours) with KspAI (see Star Activity).
Stability During Prolonged Incubation
A minimum of 0.5 units of enzyme is required for complete digestion of 1ug of lambda DNA in 16 hours at 37 degree C.
Storage Buffer
10mM Tris-HCl (pH 7.5 at 25 degree C), 50mM KCl, 1mM DTT, 0.1mM EDTA, 0.2mg/ml BSA and 50% glycerol.
Thermal Inactivation
Enzyme is inactivated by incubation at 65 degree C for 20min.

Other Notes

Small volumes of KspAI restriction enzyme vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
