KAPA Long Range is also supplied in 2X ReadyMix format with loading dye that contains all the components required for PCR except primers and template. The loading dye in the reaction buffer allows you to load PCR products directly onto the agarose gel with no extra steps.
- Amplification of long targets and/or low amounts
- Standard short- and mid-range PCR
- T-A cloning
- Targeted sample enrichment for next-generation DNA sequencing
- polymerase chain reaction (PCR)
Biochem/physiol Actions
Both KAPA Taq HotStart® DNA polymerase and a modified archaeal (Type B) DNA polymerase enzyme possess 53 polymerase activity, but only KAPA Taq HotStart DNA polymerase possesses 53 exonuclease activity and only the Type B DNA polymerase possesses 35 exonuclease (proofreading) activity. The fidelity of KAPA LongRange HotStart is 2–4 fold higher than that of Taq DNA Polymerase, but is lower than the fidelity of pure proofreading polymerases such as KAPA HiFi. Reaction products generated with KAPA LongRange HotStart are polyA-tailed and can be cloned into TA-cloning vectors.
Features and Benefits
Amplify long targets with high sensitivity:
- Amplification of targets with high sensitivity and specificity up to 15 kb
- High yields with low input DNA
Outperforms with complex targets:
- Exhibits high yield, greater sensitivity and specificity where competitor long-range systems fail
Quick Notes:
- KAPA LongRange HotStart is a blend of KAPA Taq HotStart and a proofreading DNA polymerase.
- Suitable for short-, medium- and long-range PCR, and PCR with low amounts of template DNA.
- Fidelity is 2–4 times better than Taq.For short amplicons, replace Taq DNA polymerase for improvements in yield and/or fidelity.
- Amplify mid- to long-range targets with high yield and sensitivity.
- KAPA LongRange Buffer (Mg-free) is designed for long-range, sensitive PCR. MgCl2 is supplied separately for optimization.
Quality
Each batch of KAPA LongRange HotStart DNA Polymerase is confirmed to contain <2% contaminating protein (Agilent Protein 230 Assay). The KAPA LongRange HotStart PCR system is subjected to stringent quality control tests, is free of contaminating exo- and endonuclease activity, and meets strict requirements with respect to DNA contamination levels.
Preparation Note
Always ensure that the product has been fully thawed and mixed before use. Reagents may be stored at 4°C for short-term use (up to 1 month). Return to -20°C for longterm storage.

С 2010 года мы поставляем оборудование с заводов Европы. Берем на себя все — от подбора оборудования до внедрения на предприятии

Все сотрудники имеют высшее образование, закончили ведущие химические вузы страны, такие как РХТУ им Менделеева.

У большинства компаний срок ожидания составляет 10-12 недель.

Оборудование хранится на сухом отапливаемом складе, где поддерживается ровная температура.

Работаем с PonyExpress и Деловыми линиями. Вы также можете выбрать свою транспортную компанию или забрать товар со склада в Москве.

В случае любых неполадок за свой счет выполним ремонт в сервисном центре или на заводе-изготовителе. Или бесплатно заменим прибор на новый.

Производим пуско-наладку оборудования, валидацию, обучение сотрудников. Если нужно, привлекаем инженеров с заводов- изготовителей.
