Bio-Helix Taq DNA Polymerase is purified from E. coli. expressing a Thermus aquaticus DNA polymerase gene. This enzyme has a 5′ → 3′ DNA polymerase and a 5′ → 3′ exonuclease activity but lacks a 3′ → 5′ exonuclease activity. The enzyme consists of a single polypeptide with a molecular weight of approximately 94 kDa. Taq DNA polymerase is heat-stable and will synthesize DNA at elevated temperatures from single-stranded templates in the presence of a primer. 

Taq DNA Polymerase is recommended for use in routine PCR reactions. The buffer system is optimized for high specificity and guarantees minimal by-product formation. We supplied Taq DNA Polymerase with appropriate buffers. Usually 1-1.5 u of Taq DNA Polymerase are used in 50 µl of reaction mix. Higher Taq DNA Polymerase concentrations may cause synthesis of nonspecific products. However, if inhibitors are present in the reaction mix (e.g., if the template DNA used is not highly purified), higher amounts of Taq DNA Polymerase (2-3 u) may be necessary to obtain a better yield of amplification products.

Bio-Helix has been focusing on providing the best bio-reagents for life science researchers all over the world since 2007. Our products, to name a few, include DNA markers, protein markers, staining reagents, nucleic acid purification, PCR reagents and so on.

Working together with scientists in the lab around the world and continuing efforts of quality improvement, we begin to gain trusts and appraises from customers. The brand, Bio-Helix, spreading in more than forty countries, has become a trustworthy and welcome brand of reagents in laboratories of life science.

With the expansion of product lines as well as customers, we discover a greater need for a good quality supply of bio-reagents from the medical circle. Mostly, these needs are for diagnostic products. The demand of good quality bio-reagents for diagnostic devices opens a whole new possibility of innovation and motivation for Bio-Helix.

We have a vision that one day our life span can be elongated; life quality can be improved by early detection and subsequent proper treatment of all diseases. Ancient Chinese believed that a good doctor treats the disease before illness, instead of after its onset. In Bio-Helix, a new brand, LifeDirex, is created to fulfill this vision. LifeDirex will be focusing on supplying the best and most innovative reagents for diagnostic tools to promote the earliest detection of diseases as possible.

Our mission is to provide the best quality products and to develop novel technologies that assist researchers to find solutions in quest of scientific achievements. Furthermore, we decide now is the best time to enter the market of in vitro diagnostic device (IVDD). It is our goal to become the best solution provider for both research laboratory and IVDD.

Driven by desires to improve life quality and achieve scientific excellence, we operate with the highest standards of integrity. We also extend the spirit to our services and global value to our customers all around the world. A diverse workforce and network of collaboration from a great mix of company culture. Bio-Helix is not only a company of equal opportunity but also works hard to provide a friendly and growing environment.
