Stable Cell Lines

Download Flyer for Stable Cell Lines (PDF)


Stable cell lines are one of the most used tools in drug discovery, toxicity testing, and basic research. Long-term stable expression of a gene of interest is usually achieved by transfection or viral transduction of a vector containing the expression cassette of the gene of interest together with a selection marker (antibiotics or fluorescent proteins). In contrast to transient expression, stable cell lines offer reproducible results for assay studies in drug discovery and development.

As One’s Most Popular PCR Enzymes

AS ONE High Fidelity DNA Polymerase is a thermostable enzyme with proofreading ability. The High Fidelity-Taq has 16x greater fidelity than Taq polymerase.

AS ONE Hot Start Taq DNA Polymerase is a modified form of AS ONE Taq DNA Polymerase, which is activated by heat treatment. During setup and the first ramp of thermal cycling, the enzyme is not active so misprimed primers are not extended.

AS ONE 2X Master Mixes conveniently includes Taq polymerase, NH4+ buffer system, dNTPs and magnesium chloride.

AS ONE Taq DNA Polymerase is a thermostable recombinant DNA polymerase, which exhibits very high activity in primer extension and other molecular biology applications.

PSP® SalivaGene DNA Kit

PSP SalivaGene DNA Kit

The PSP® SalivaGene DNA Kit used with the SalivaGene® Stabilization Collection Tubes is a modular system, combining a DNA stabilization solution for collection, stabilization, storage and transportation of saliva or swab material with a very efficient isolation method for high quality DNA.


5 Easy Steps from sample to purified DNA!

For the isolation of genomic host DNA, mitochondrial DNA, pathogenic bacterial and eukaryote DNA from swab and saliva samples.

Field Applications: forensic, human-identity, genetic, biosecurity, pathogen, in vitro diagnostic, pharmacogenomics, and microbiome analysis.


SalivaGene Sample Collection Tubes

SalivaGene sample collection tubes containing DNA Stabilizer keeps DNA stable for 12 months at RT or –20°C for years! The DNA stabilization buffer preserves the microorganism titer by prelysis of bacteria, inactivating DNases and preventing DNA degradation.

Purification Kits for PCR Products & DNA Fragments

MSB Technology

MSB® (minimal salt binding) technology, the fastest technology for purification of DNA fragments with high recovery rates. The MSB® kits have been designed for extremely efficient purification and concentration of PCR products or of DNA fragments from enzymatic reaction mixtures with only two steps. The DNA fragments adsorb at the silica membrane in the presence of minimal concentrations of non chaotropic salts, while impurities pass through the column. Then the DNA fragments are eluted in a low-salt buffer or water. Therefore a washing step is not required.


MSB Spin PCRapace Kit

MSB Spin PCRapace Kit is a powerful tool to clean up and concentration PCR products or DNA fragments. Just two simple steps — binding, elution — from crude sample to pure DNA


We are offering a 12% discount for the following kits until August 31, 2018.

Catalog # 1020220300: MSB Spin PCRapace, 250 purifications

Catalog # 1020220400: MSB Spin PCRapace, 500 purifications


Invisorb Technology

Invisorb® technology is the first technology for the extraction of highly purified nucleic acids using non chaotropic binding conditions. Starting from complex biological samples, the method allows binding of nucleic acids to nearly all surfaces, such as membranes, carrier or magnetic particles. In combination with specially modified surfaces a selective binding of different nucleic acid targets can be realized.


Invisorb Fragment Cleanup

The Invisorb® Fragment CleanUp provides a convenient tool for fast and efficient purification of PCR products and DNA fragments.

Invisorb Fragment Cleanup kit combines 2 Stratec technologies in 1 kit – MSB technology for PCR or DNA fragment cleanup. DNA fragments bind to a silica membrane while the contaminants flow through. Target DNA fragments are eluted in a low-salt buffer or water. Invisorb technology is used for purification of DNA fragments from agarose gels, the DNA fragments are bound to the surface of the spin filter column after the gel is solubilized.
