Cesium Klentaq C LA is a cold-sensitive mutant of Klentaq1 (5"-exonuclease deficient Taq polymerase with improved fidelity and thermostability) with the Long-and-Accurate feature that allows amplification of longer products with higher fidelity and accuracy. Due to its suppressed activity at low temperatures this enzyme is designed for hot start PCR performance.  LA enzymes are not recommended for use with dUTP.
