Tips for Optimizing Immunofluorescence Protocols to Get the Best Image
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.
Gold Nanoparticles: Properties and Applications
Gold (Au) nanoparticles have tunable optical and electronic properties and are used in a number of applications including photovoltaics, sensors, drug delivery & catalysis.
How Suppliers Impact your ISO 13485:2016 Quality Management System
Enhanced ISO 13485 requirements for IVDs must be implemented by the February 28, 2019 deadline.
Supply chain considerations when developing or manufacturing your IVD assay
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.
10 Strategic Considerations When Outsourcing Production of In Vitro Diagnostics
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

How to Determine the Best Product & Supplier for Proteinase K
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
PCR-based Assay Regulations and Validation
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
Qualitative multiplex PCR assay for assessing DNA quality from FFPE tissues and other sources of damaged DNA
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
