Recognition sequence: 5′-GGTAC/C-3′
Cutting results: a 2-10-fold Kpn I overdigestion of 1 μg λ DNA substrate results in 100% cutting
Heat inactivation: 65 °C for 15 minutes.


KpnI is a DNA restriction enzyme that is used in molecular biology research to cleave DNA at the recognition sequence 5′-GGTAC/C-3′ to generate DNA fragments with 3′-cohesive termini.

Other Notes

Supplied with 10x Restriction Enzyme Buffer SL (B3782)
Comment: Kpn I shows abnormal DNA cleaving patterns (star activity) in reactions containing high (>5%) glycerol, >5% (v/v); excess enzyme and high pH (>8.0).
The enzyme will not cleave DNA containing 3′-residue of 5-methylcytosine.

Physical form

Solution in 20 mM Tris-HCl, pH 7.5, 0.1 mM EDTA, 50 mM NaCl, 10 mM 2-mercaptoethanol, 50% glycerol (v/v), 0.01% polydocanol (v/v) at 4°C

Mice lacking the 80-kDa CD2-associated protein (CD2AP) develop progressive renal failure that starts soon after birth with proteinuria and foot process effacement by unknown mechanisms. CD2AP has been identified and cloned independently by virtue of its interaction with the T...

Androgens control spermatogenesis, but germ cells themselves do not express a functional androgen receptor (AR). Androgen regulation is thought to be mediated by Sertoli and peritubular myoid cells, but their relative roles and the mechanisms involved remain largely unknown. Using...

We have determined the recognition sequence of the restriction endonuclease KpnI, previously isolated from Klebsiella pneumoniae. The enzyme cleaves the twofold rotationally symmetric sequence (see book for formula) at the positions indicated by the arrows, producing 3' protruding cohesive ends...
