Why is VeraSeq 2.0 DNA Polymerase sometimes cloudy upon removing from -20°C storage?

VeraSeq™ 2.0 High-Fidelity DNA Polymerase is an engineered, ultra-thermostable polymerase that delivers industry-leading speed, fidelity and robustness to PCR amplification. The novel enzyme can extend a kilobase of sequence in 15 seconds and with an accuracy 50 times higher than Taq DNA Polymerase. Supplied in: 20 mM Tris·HCl, 100 mM KCl, 1 mM DTT, 0.1 mM EDTA, Stabilizer and 50% glycerol; pH 7.4 at 25°C. Supplied with: 5x VeraSeq™ Buffer II (B7102L) and 5x VeraSeq™ GC Buffer (B7130L). You can also ask us about low glycerol or hot-start formulations.
