The 1Kbp DNA Ladder marker consists of 8DNA fragments ranging from 1Kbp to 10Kbp(10000bp, 8000bp, 6000bp 5000bp, 4000bp, 3000bp, 2000bp and 1000bp, the 4000bp fragment is 100ng, others are all 50ng).
The Hot Start Taq DNA Polymerase is a recombinant Taq DNA polymerase that has been chemically modified by the addition of heat-labile blocking groups to its amino acid residues.
