商品介绍

Human Topoisomerase II alpha and beta

Click on the product headings below to view details and order online.

Human Topoisomerase II Alpha

>

Human topoisomerase II alpha is prepared by overexpressing in baculovirus-infected insect cells (Spodoptera frugiperda) and purifying it by methods developed in-house.

The enzyme is supplied in Dilution Buffer.

Store at -80°C.

It is recommended that larger pack sizes (500U and above) of the enzyme are aliquoted to avoid repeated freeze-thaw cycles.

See technical documents below for more detailed information and lot specific activities.

Inspiralis


Inspiralis在提供高质量拓扑异构酶,连接酶和解旋酶方面享誉全球,包括检测试剂盒,底物和筛选服务。


We are located in laboratories adjacent to the academic research centres of the John Innes Centre and the University of East Anglia on the Norwich Research Park. We maintain close links with the academic research group of Professor Maxwell, helping us to remain at the forefront of the topoisomerase field. The experience of our staff and the connections with the academic group allow us to provide a high level of support to ensure that researchers are able to get the best results using our products. The same scientists who produce our enzymes and substrates also provide the technical support.


Our aim is to provide pharmaceutical companies, and others involved in drug development, with the necessary tools to develop and screen novel anti-infective and anti-cancer compounds. In order to achieve this we will continue to expand the range of topoisomerase products and screening services we offer.
