A specially formulated solution designed to amplify long DNA fragments. It combines two thermostable DNA polymerases, the standard Taq x-VITA and the proofreading x-VITA. It can amplify long DNA chains, such as the λ phage genome, of up to 20 kb. It’s also a superior choice for amplifying complex templates, particularly those with a high GC content. The elongation rate is 3 kb/min. The generated products consist of a mixture of 3′-dA overhang and blunt-end products, which can be used in TA cloning
