The LA Taq DNA Polymerase is a kind of Long PCR Polymerase that synergistically generates long PCR products with greater yield and fidelity than Taq DNA Polymerase alone.
The 2×TaqMan Master Mix is a special mixture for Probe real-time PCR(TaqMan, Molecular Beacon, etc.). Which include the HotStar DNA Polymerase, PCR Buffer, MgCl2, dNTPs, ROX, and the stabilizing agent.
The 50bp DNA Step Ladder consists of 8 DNA fragments ranging from 50bp to 500bp (50bp, 100bp, 150bp, 200bp, 250bp, 300bp, 400bp, 500bp, 550bp, the 250bp is 100ng, others are all 50ng).
