New and Improved Rotavirus Now Available!

Microbix is pleased to announce the availability of a new and improved Rotavirus antigen. Rotavirus Grade 3 Antigen (Cat# EL-35-03) replaces all previous rotavirus antigens, including EL-35-02 and EL-35-AA.

Microbix has developed an improved purification process and inactivation procedure for EL-35-03. The product has higher purity and superior antigen titre and performance in most immunoassays compared to EL-35-02 (which has been discontinued).

EL-35-03 is designed for use in immunoassays and positive control preparations in antigen detection assays like point-of-care tests and molecular assays. It contains predominantly intact viral particles as well as free viral antigens and some non-viral proteins. This antigen can be diluted significantly in most applications making it a cost effective positive sample for your assay.

We have plenty of rotavirus in stock, please contact us with any questions or if you would like to test a sample of this great new antigen.

We’re doing a lot with Chlamydia these days.

Microbix has produced Chlamydia trachomatis since 1995 and Chlamydia pneumoniae since 2001. Both are primarily used as antigens in commercial diagnostic tests sold around the world.

We’ve recently been working to improve the release assays for these products and expect to have new specifications based on MOMP concentration and IFU. These improvements should be complete in June 2013.

On a related note Microbix has been performing custom culture and purification work with various Chlamydiae strains. If you have an isolate or strain you are looking to have characterized, banked, cultured and tested we would be happy to discuss our expertise with you.

Update on Dengue Program

Based on the field tests and data generated in house from our first round of dengue NS1 and multi-serotype preparations, we have concluded there is room for improvement on these antigens. We are pursuing an alternate strategy that we believe will generate native purified NS1 that significantly outperforms recombinant antigen.

Likewise, we have generated samples of DEN 1-4 lysate. We are working to optimize these cultures and purify viral particles. Stay tuned for updates on these new antigens.

We have plenty of inactivated DEN-2 in stock (Cat# EL-22-02) and this antigen is ideal for ELISA. This product has a good concentration of NS1 and is used as the positive control in several commercial NS1 early dengue detection assays.

Microbix Now Using Modified Catalogue Numbers

Effective January 2011, customers should note a change in the calaogue numebr for all antigens. We have started using a suffix that denotes the packaging size for all items. This will allow customers to specify the packaging confirmation for their products.

An example of this using CMV Grade 2:

EL-01-02-001.0     CMV Grade 2, 1 mL

EL-01-02-010.0     CMV Grade 2, 10 mL

EL-01-02-050.0     CMV Grade 2, 50 mL
