Summary	Creative Biogene ensures high-quality adenovirus particles by optimizing and standardizing production protocols and performing stringent quality control (QC). The specific QC experiments performed vary between adenovirus particle lots.
Endotoxin	Endotoxins, primarily derived from Gram-negative bacteria, can trigger adverse immune responses. Endotoxin contamination is a significant concern in adenovirus production, especially for applications in animal studies and gene therapy. Creative Biogene utilizes rigorous endotoxin detection methods to monitor the endotoxin level in our produced adenovirus particles to ensure regulatory compliance.
Sterility	Creative Biogene ensures that adenovirus products are free of any bacterial, fungal and other microbial contamination.
Ad5 E1 Detection	All Creative Biogene adenoviruses are PCR tested to ensure that there are no detectable E1 sequences in the particles, which could be from revertants or external E1 contamination.
RCA Assays	Adenovirus products originating at Creative Biogene are guaranteed to have undetectable replication-competent adenovirus (RCA). This quality control measure is important because there is always the possibility of wild-type contamination due to revertants or environmental sources.
PFU Titering	All purified adenovirus preparations are tested for infectious titer. Creative Biogene's PFU test takes a few days longer but counts true plaques in HEK cells rather than estimating PFU titers via IHC staining or TCI50 of infected cells.

Target Gene

PREX2

Background

The protein encoded by this gene belongs to the phosphatidylinositol 3,4,5-trisphosphate (PIP3)-dependent Rac exchanger (PREX) family, which are Dbl-type guanine-nucleotide exchange factors for Rac family small G proteins. Structural domains of this protein include the catalytic diffuse B-cell lymphoma homology and pleckstrin homology (DHPH) domain, two disheveled, EGL-10, and pleckstrin homology (DEP) domains, two PDZ domains, and a C-terminal inositol polyphosphate-4 phosphatase (IP4P) domain that is found in one of the isoforms. This protein facilitates the exchange of GDP for GTP on Rac1, allowing the GTP-bound Rac1 to activate downstream effectors. Studies also show that the pleckstrin homology domain of this protein interacts with the phosphatase and tensin homolog (PTEN) gene product to inhibit PTEN phosphatase activity, thus activating the phosphoinositide-3 kinase (PI3K) signaling pathway. Conversely, the PTEN gene product has also been shown to inhibit the GEF activity of this protein. This gene plays a role in insulin-signaling pathways, and either mutations or overexpression of this gene have been observed in some cancers. [provided by RefSeq, Apr 2016]
