A. baumannii Topoisomerase IV

Topo IV (from Acinetobacter baumannii) is prepared by overexpressing the subunits in E. coli and purifying them by methods developed in-house.

The subunits are purified to >95% purity as judged by SDS-PAGE. The topo IV is supplied as a heterotetramer complex in Dilution buffer.

It is recommended that the enzyme is aliquoted to avoid repeated freeze-thaw cycles. Store at -80ºC.

All enzyme is supplied with 5X concentrated Assay Buffer and Dilution buffers which are also available separately.

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

品牌介绍

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.
