FLEX-ARRAYs

IHC / IF / F/ISH

Our team is highly experienced in classical and advanced immunohistochemical and in situ hybridization methods on cells and tissues as well as single target and multiplexed IF/FISH techniques with a particular emphasis on FFPE material.  Very few laboratories have our depth of experience in these advanced techniques and process controls.

 MULTIPLEXED assays

​​Advanced in situ detection methods  
Critical X is your source for tissue-based assay development, sample processing, testing, and pathology consultation services for basic and clinical research.  See below for a high level summary of technologies and feel free to reach out to us to learn more...

Tissue study design support and technical consulting
After initial consultation, our team will work with you to create a project proposal that will define our scope and expected outcomes for your project.  We then get to work to plan and work side-by-side with your team where necessary to achieve your goals.  We do this by defining clear targets, expectations and controls from the start and after that, it is about accountable execution on quality and agreed upon turn-around-times.
