Applications
CSF — Neurological Biomarkers
CSF is the primary matrix for Alzheimer's and Parkinson's diagnostics — tau, phospho-tau, amyloid-β42, neurofilament light chain (NFL). Our CSF is collected under standardised lumbar puncture conditions with full traceability.
CLSI EP9 Matrix Comparison
Same-donor anticoagulant quartets and quintets — collected from a single donation session — for CLSI EP9 matrix comparison studies demonstrating assay equivalence across different sample types for IVDR submissions.
FFPE Tissue — Companion Diagnostics
FFPE tumour tissue for IHC/ISH validation, biomarker expression characterisation and companion diagnostic (CDx) development — various tumour types available on request.
Frequently Asked Questions
What is the lead time for fresh frozen tissue?
Fresh frozen tissue requires advance coordination with the collection site and scheduling with the tissue bank. Typical lead time: 4–8 weeks depending on tissue type and quantity. Contact us early in your project planning to confirm availability and timeline.
What documentation is included with tissue samples?
All tissue samples include full ethical clearance, IRB/ethics board documentation, donor informed consent framework, chain-of-custody documentation, and basic pathological characterisation (for FFPE tumour tissue). Extended documentation is available on request.
Are the anticoagulant panels suitable for IVDR performance evaluation?
Yes — the same-donor anticoagulant quartet and quintet panels are designed for CLSI EP9 matrix comparison studies, which are used in IVDR performance evaluation studies to demonstrate equivalence of results across different sample tube types. The same-donor design eliminates inter-individual biological variation as a confounding factor.
