50bp plus DNA Ladder RTU (DM017-R500) is a 17 fragments molecular weight standard for agarose gel electrophoresis. Using the unique combination of a number of proprietary plasmids digested with appropriate restriction enzymes and PCR products yields fragments ranging from 50-1,500 base pairs. The 4 bands at 500, 1000, 1200, and 1500 base pairs have specifically increased in intensity to serve as the reference bands. The approximate mass of DNA in each band is provided (0.7405μg per load) for approximating the mass of DNA in comparably intense samples of similar size.

 

Source: PCR products and double-stranded DNA digested with appropriate restriction enzymes are phenol extracted and equilibrated to 10 mM Tris-HCl and 10mM EDTA at pH 8.0.

Reaction Setup: 5 μl / well ( **Containing bromophenol blue & xylene cyanol FF as tracking dyes. )

Range : 50 – 1,500 bps

Number of bands: 17

Storage :
Store at 4°C for 12 months
Store at -20°C for 24 months

 

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.
