What are tumor marker–associated biospecimens?

Tumor marker–associated biospecimens are human samples such as serum, plasma, whole blood, or tissues that include documented levels of specific cancer-related biomarkers. These samples help researchers study cancer progression, validate diagnostic tools, and explore biomarker-based disease detection strategies.

Which tumor markers are available through Centrallink?

Centrallink offers biospecimens linked to a wide range of tumor markers, including CEA, CA 19-9, CA 15-3, CA-125, PSA, AFP, ß-hCG, NSE, and additional oncology-relevant biomarkers. Availability varies by diagnosis, cancer type, and clinical metadata.

How are tumor marker biospecimens collected and processed?

All tumor marker–associated samples are collected through accredited clinical partners under strict ethical guidelines and IRB/Ethics Committee approvals. Each specimen is processed following standardized laboratory protocols to ensure reliable tumor marker values and high integrity for research use.

What research applications use tumor marker biospecimens?

Tumor marker biospecimens are widely used in oncology and diagnostic research, including biomarker validation, assay development, early cancer detection studies, therapeutic monitoring, and multi-omics analyses such as genomics and proteomics.

Can I request custom or rare tumor marker samples?

Yes. Centrallink supports custom procurement for researchers requiring rare cancer markers, specific tumor marker ranges, longitudinal samples, or matched specimen sets. Our scientific support team collaborates with global clinical sites to fulfill specialized oncology research needs.

What types of infectious disease biospecimens does Centrallink offer?

Centrallink provides serum, plasma, whole blood, swabs, tissues, PBMCs, DNA, RNA, and other biospecimens associated with viral, bacterial, fungal, and parasitic infections.

What clinical data is available with infectious disease biospecimens?

Samples may include antibody titers, antigen positivity, viral load, PCR results, serotype information, diagnostic data, and patient clinical history, depending on availability.

How are infectious disease biospecimens collected and preserved?

All samples are collected under IRB/Ethics Committee approval and processed using standardized procedures to maintain pathogen integrity, immune markers, and analytic quality.

What research applications use infectious disease biospecimens?

These biospecimens support diagnostics development, vaccine research, biomarker discovery, pathogen detection, serological testing, epidemiology studies, and translational infectious disease research.

Can I request custom infectious disease samples or rare pathogen cohorts?

Yes. Centrallink offers custom sourcing for rare pathogens, matched cohorts, longitudinal samples, specific titer ranges, and specialized diagnostic requirements.
