LAM PCR Service

The application of viral vectors in gene therapy is rapidly developing and the therapeutic results are highly promising. However, actively and passively integrating (viral) vectors may fail to deliver, or trigger severe side effects by undirected or unintended integration into the genome of the target cell. Thus, the analysis of vector integration sites in target cells is extremely important to address both biological and safety issues. Creative Biogene, as a leading biotechnology company in the world, has extensive expertise and experience which are available to provide you with customer LAM PCR service to analyze the viral vector insertion/integration site.

LAM PCR service

LAM PCR (Linear - amplification mediated PCR) is a technology which is used for identifying and characterizing unknown flanking DNA adjacent to known DNA of any origin. More specifically, LAM-PCR has been developed to localize viral vector integration sites (IS) within the host genome [1, 2]. Genetic elements like retroviruses or transposons integrate their genome into the host genome in a (semi-) random manner [3-6]. In many cases, it is decisive to know exactly the position where these vectors integrated. With years of development, Creative Biogene has set up mature assays for several vectors, including lentiviral and most oncoviral vectors, sleeping beauty transposons, and some AAV-related vectors, etc.. Creative Biogene’s goal is to provide you with the most affordable, high-quality LAM PCR services to ensure your satisfaction in a timely and professional manner.
