From FFPE and frozen human tissue blocks to whole blood, plasma, serum, and PBMCs, access a comprehensive catalog of high-quality biospecimens processed for optimal performance in your assays.
The success of any research project fundamentally depends on the integrity of its biological samples. At iProcess, we provide a wide range of meticulously collected and preserved human tissue and biofluid samples. Our standardized protocols ensure that every specimen, whether it’s brain tissue for neurological studies or human blood for biomarker discovery, maintains the highest quality from collection to delivery. We are committed to being your strategic partner, providing not just samples, but the confidence and consistency your science demands to move from the lab to the clinic.
Human tissue is fundamental to understanding the cellular architecture of disease. We offer tissue in three key formats: fresh, for immediate cell-based assays; frozen (snap-frozen), which preserves the integrity of proteins and RNA for genomics and proteomics studies; and formalin-fixed paraffin-embedded (FFPE), the gold standard for histology and long-term storage. Our FFPE blocks are prepared to ensure morphological and molecular preservation, making them ideal for techniques like IHC and ISH. Each tissue sample, regardless of its format, is linked to comprehensive clinical and pathological data, providing essential context for your findings.
Liquid biopsies are a powerful and minimally invasive tool. We provide human blood products collected in various anticoagulants (EDTA, Heparin, etc.) to suit your application. Whole blood is ideal for direct genomic analysis. Plasma, rich in clotting factors and proteins, is perfect for biomarker discovery and pharmacokinetic studies. Serum, devoid of clotting factors, is the sample of choice for immunoassays, serology, and metabolomics. We rigorously control pre-analytical variables to ensure high purity, minimal hemolysis, and maximum reliability of your results, delivering analysis-ready samples.
PBMCs are a vital component for research in immuno-oncology, infectious diseases, and vaccine development. We isolate our PBMCs from fresh whole blood using density gradient centrifugation, a method that guarantees high purity and cell viability. These cells are fundamental for a variety of functional assays, such as ELISpot, flow cytometry, and cell proliferation studies. We offer cryopreserved vials of PBMCs from healthy and diverse patient donors, each accompanied by a certificate of analysis detailing cell count, post-thaw viability, and donor clinical data, making them an indispensable resource for immunotherapy.
Beyond blood, we offer a wide range of biofluids for various research applications. Urine and saliva are excellent for non-invasive biomarker discovery. Stool is crucial for microbiome research and its impact on health and disease. Sputum is valuable for studying respiratory pathologies, while swabs are essential for collecting samples from various body surfaces for infectious disease and genetic studies. Each of these sample types is collected using standardized kits and protocols to ensure stability and quality, opening new avenues for your research.
Our capabilities go beyond our extensive inventory. We excel at managing challenging logistical and scientific projects to deliver the precise biospecimens our clients need. These case studies demonstrate our commitment to quality and our ability to execute under demanding circumstances.

Choosing the right biospecimen is crucial for the success of your experiment. Below, we detail the primary research applications and key technical considerations for each of our main specimen types to help you select the ideal format for your scientific goals.
Custom Collection and Processing Services
Your research is unique, and your biospecimens should be too. We offer prospective collection and custom processing services to meet the specific requirements of your study. Our team of scientists can work with you to design a custom protocol, obtain specific consents, and process samples to your needs, ensuring you get the exact biological materials your science demands.
Biological samples, or biospecimens, are materials from the human body used in research. Examples include solid human tissue (like tumors), blood and its components (plasma, serum, and PBMCs), and other biofluids like saliva, urine, and cerebrospinal fluid (CSF). iProcess offers a comprehensive catalog of these biospecimens to support a wide array of research applications.
Human tissue collection is a precise medical procedure where samples are obtained via biopsy or surgery. For research, this includes immediate, protocol-driven handling and preservation. iProcess specializes in prospective, custom collection, where we work with you to create and execute a unique protocol to meet your exact research needs.
In research, human tissue samples are mainly defined by their preservation. The most common types are FFPE (formalin-fixed paraffin-embedded) for studying tissue structure and frozen tissue for molecular analysis. iProcess provides tissue in fresh, frozen, and FFPE formats, allowing you to select the ideal option for your assay, from cell-based studies to genomics.
The two gold-standard methods are formalin fixation for FFPE blocks and snap-freezing. FFPE preserves the tissue’s structure for histological analysis , while snap-freezing better maintains the integrity of proteins and RNA for ‘omics’ studies. iProcess employs strict, standardized protocols for both methods, minimizing variables like ischemia time to ensure the highest quality preservation.
The four primary biological tissue types are epithelial, connective, muscle, and nervous tissue. Diseases are often classified by their tissue of origin. iProcess’s extensive biobank contains diseased and healthy samples from across these categories, including nervous tissue for neurology studies and a vast portfolio of epithelial tumors (carcinomas) for oncology research.
