Advanced BiotekServices (ABTEK) provides bio-technical services to support researchers and scientists in academia and industries. The following are our featured services that interest many researchers. For a complete list of our services please go to SERVICES.
Construction of cDNA Libraries
We have a proprietary technology to construct cDNA libraries. Using this technology, we are able to directionally clone cDNA into almost any types of expression vectors without cutting the cDNA with restriction enzymes. Therefore, the cDNA libraries we constructed have higher complexities and more full length clones than the others'.
Making Stable Expression Cell Lines
We provide services to make stably transformed cell lines. One of the methods we are using is to deliver a foreign gene into the target cells with lentivral vectors. Lentiviral protein-mediated integration renders long term expression of foreign genes in the target cells.
Screen of cDNA Libraries
We perform cDNA library screen for researchers to discover their proteins of interest. Our screen methods are based on either proteins or cellular functions. These methods have been used to make many break through discoveries.
Synthesis of RNA
We provide services to synthesize a variety of RNA by in vitro transcription. The mRNA that we synthesize is capped and has a long poly(A) tail of more than 50 adenine nucleotides. It is particularly suitable for in vivo protein synthesis.
Protein Production and Purification
We use mammalian cells to produce biologically active proteins with non-infectious vaccinia expression systems. Our services satisfy your needs for a single protein as well as high throughput production of tens and hundreds of different proteins.
Antibody Cloning and Expression
We have a proprietary technology to clone the heavy (H) and light (L) chain cDNA of antibodies from hybridoma cells. With this technology, we are able to clone H and L cDNA even from low antibody-expression hybridoma cells.
