Uses for immunofluorescence (IF)—where an antibody conjugated to a molecule that fluoresces when excited by lasers— include protein localization, confirmation of post-translational modification or activation, and proximity to/complexing with other proteins.
The recent pandemic has highlighted that strong supply chain management should be a vital consideration for any potential clinical diagnostic CMO partner as the risk of regional and global disruptions are unlikely to disappear.
The choice of whether to outsource production of an in vitro diagnostic (IVD) or invest and develop in-house capabilities is a foundational business decision. We highlight 10 important benefits of outsourcing and key considerations that should factor into the evaluation
Elypta partnered with us to produce the first standardized extraction kit for GAG quantification in bodily fluids for research use. Our contract manufacturing services move Elypta one step closer to meeting growing customer demands for this novel research assay as
In May 2017, the European Union’s In Vitro Device Regulation (IVDR 2017/746) went into effect, replacing the In Vitro Diagnostic Device Directive (IVDD). The new regulation is more comprehensive than the IVDD and was introduced to reduce inconsistencies in the
A case study describing how Mammoth Biosciences, a diagnostics company utilizing CRISPR gene editing collaborated with MilliporeSigma for manufacturing scale-up expertise and critical raw material supply chain security to ensure a successful launch and long-term success of their novel SARS
The cost of proteinase K can vary depending on the source, purity, manufacturing process and vendor’s quality management system. It is important to balance the cost with the desired quality, performance, documentation and technical/quality support to select the optimal Proteinase
While many PCR assays are developed for research applications there are further considerations for those that are being developed to become diagnostic assays or to be performed in support of: Biologics License Application (BLA), New Drug Application (NDA), Premarket Approval
The assessment of DNA quality is a crucial first step in acquiring meaningful data from formalin-fixed paraffin-embedded (FFPE) tissues, and other sources of damaged DNA. Using intact genomic DNA is key for successful analysis of chromosomal aberrations (e.g. SNP analysis
The use of Pro K in combination with other reagents, such as detergents and chaotropic agents, can help to disrupt the cell membranes and release DNA from tissue. This is particularly important for downstream applications such as PCR, sequencing, and
In blood DNA extraction, Proteinase K, an enzyme commonly used to degrade proteins, can help break down the cellular and nuclear membranes, releasing DNA from the cells that protect it from degradation and increase purity/yield making it more suitable for
While the commercialization pathway for IVD devices is complicated, a knowledgeable contract manufacturing partner can save significant time, money, and aggravation by providing design, quality, and regulatory assistance.
Steven J. Oldenburg, Ph.D. provides an overview of lateral flow diagnostic assays and discusses the use of ultra-bright reporter particles based on the unique optical properties of gold nanoshells that significantly increase the sensitivity of lateral flow immunoassays.
