Proofreading capability enables high sensitivity, accuracy and low amplification from small size DNA to DNA of more than 20Kb    

  • • Dried & aliquoted PreMix, All-in-one products
       - Immediate PCR by adding template and primer
       - Gel loading electrophoresis is possible because it contains loading dye
  • • Excellent product stability and reproducibility   
       - Excellent reproducibility with dried & aliquoted PreMix by ALHP system  
       - Excellent stability due to oxidation and moisture prevention by vacuum compression manufacturing method  
  • • High accuracy and low error rate
       - Proof-reading activity enables amplification of long DNA template
       - Ensures high amplification efficiency for amplification of long and short template DNA
  • • Cloned DNA, human genomic DNA, as well as GC-rich or looped sequences that are difficult to amplify  can be applied to various DNA

All components (dNTP mixture, reaction buffer, etc.) necessary for PCR reaction, including i-MAXTM II DNA Polymerase, are included in each PCR tube by the ALHP system, and the dried pellet Because it is in the state, it can remarkably reduce the experimental error to pipetting between the experimenter, and it has excellent reproducibility. It is a product with excellent stability of activity due to the oxidation and moisture prevention of main components in the product by vacuum compression manufacturing method . In addition, this product can perform PCR by adding template DNA, primer set and D.W only, and it can contain gel loading buffer. The i-MAXTM II DNA Polymerase used in this product has the advantages of Taq DNA Polymerase and Pfu DNA Polymerase to overcome the disadvantages of each enzyme and to obtain new functions. In the case of Taq DNA Polymerase, if the template is over 5 Kb, the efficiency of amplification is significantly lowered. Depending on the type of template, DNA template of 10 Kb or more is difficult to amplify. This is because Taq DNA Polymerase has no proof-reading activity, and when mismatched nucleotides are inserted during DNA synthesis, the template fails to polymerize. These defects in Taq DNA Polymerase can be overcome by using a thermostable DNA polymerase with corrective function.

This corrective function is to remove the mismatched (non-complementary) nucleotide when the DNA Polymerase undergoes a polymerization reaction, and correct it with a complementary nucleotide. This activity allows PCR products of more accurate base sequences to be obtained than Taq DNA Polymerase, but allows amplification of longer DNA templates compared to Taq DNA Polymerase. Pfu DNA Polymerase is a typical enzyme of thermostable DNA Polymerase with this corrective function. It is suitable for long size PCR (up to ~ 30 Kb), which is difficult to amplify with general Taq. It has higher fidelity and proof reading function than general Taq DNA Polymerase . However, Pfu DNA Polymerase has the disadvantage that it takes more time to polymerize the DNA due to its poor polymerization efficiency. Maxime ™ PCR PreMix Kit (i-MAX ™ II) can be used for small size (4 ~ 5Kb or less) using i-MAX ™ II DNA Polymerase which takes advantages of Taq DNA Polymerase and Pfu DNA Polymerase. It not only increases the amplification rate but also gives excellent results in the sensitive part. All components required for the PCR reaction are in a dried pellet state in one tube, so you can test very quickly and easily on various samples.

TroubleShooting Guide
QI want to clone for genomic sequencing.
AIntron's i-StarMAX™ II DNA Polymerase is a DNA Polymerase made with intron's know-how using recombinant DNA technology. It has a nonspecific reaction and error rate And it is very useful to PCR a long template of 20kb or longer.
QI am currently trying to clone TA by obtaining a product from genomic DNA. In my experience, I know that even though pfu is part of cloning, I just went ahead and do not get any results. A tailing possible polymerase recommendation. 
ATA cloning is possible even with our i-StarMAXTM II. However, if you focus on TA cloning, i-Taq ™ plus is recommended.
QWhat is the difference between i-StarMAXII ™ and i-MAXTM II ?
Ai-StarMAXTM II is capable of long PCR of 20kb or more with hot start function. On the other hand, i-MAXTM II has a hot start function It can be used when you want to obtain long size product without having. 
QI am using Maxime i-StarMAXTM II. I want to increase the amount of PCR reaction. Is it OK to increase the amount of reaction by collecting the amount of two tubes into one tube?
AIf you keep the ratio of the amount of reaction, it will not affect the result. However, since the reaction solution may cause sample contamination, proceed with the manual method provided. If you want to control the reaction solution, please purchase 2X PCR Master mix type (25174).
