- Extraction and amplification from mouse tail, ear, and toe tissue
- Extraction and amplification of DNA from other animal tissues
Biochem/physiol Actions
KAPA2G Fast Genotyping Mix generated DNA fragments are 3-dA-tailed and may be cloned into TA cloning vectors, or used for routine downstream analyses or applications, including restriction enzyme digestion, cloning and sequencing. Like wild-type Taq, KAPA2G Fast has 53 polymerase and 53 exonuclease activities, but no 35 exonuclease (proofreading) activity. The fidelity of KAPA2G Fast is similar to that of wild-type Taq; it has an error rate of approximately 1 error per 1.7 x 105 nucleotides incorporated. Unlike existing protocols that rely on Proteinase K digestion, extractions using KAPA Express Extract are conveniently performed in a single tube, without the need for hazardous chemicals, or multiple wash steps.
Features and Benefits
Increased throughput, turnaround time and reliability:
- PCR-ready DNA generated in as little as 15 minutes
- Minimal handling, thereby reducing the risk of sample loss or contamination
- Sufficient template for multiple assays; easily scaled to handle samples in a 96-well format
- Fast and reliable amplification of DNA fragments across a wide range of amplicon lengths and GC contents
Outperforms crude extraction methods and commercial kits:
- Increased turnaround times
- Increased specificity
- Decreased cost
Quick Notes:
- Extract PCR-ready DNA from mouse tail, ear, or toe tissue in 15 minutes
- Dilute DNA extract 10-fold prior to PCR in 10 mM Tris-HCl (pH 8.0-8.5), and use 1 µL of DNA per 25 µL reaction.
- Extracts are stable at -20°C for >6 months.
- KAPA2G Fast (HotStart) Genotyping Mix contains the engineered KAPA2G Fast DNA Polymerase for fast PCR, along with buffer, MgCl2 (1.5 mM at 1X), and dNTPs (0.2 mM each at 1X).
- Loading dye for electrophoresis is included in the KAPA2G Fast Genotyping Mix, which allows direct loading of PCR products onto agarose gels for analysis.
- Use 15 sec annealing time, with 15 sec extension time for amplicons <1 kb, or 15-30 sec/kb extension for longer amplicons.
Packaging
- 2X KAPA2G Fast Standard or HotStart Genotyping Mix with dye
Quality
All components contained with KAPA2G Fast HotStart Mouse Genotyping Kits are subjected to stringent quality control tests, are free of contaminating exo- and endonuclease activities and meet strict requirements with respect to DNA contamination.
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 long-term storage. Provided that all components have been handled carefully and not contaminated, the kit is not expected to be compromised if left (unintentionally) at room temperature for a short period of time (up to 3 days).

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.
