Flash-frozen Tissue - Intact Biological Preservation
We support the advancement of your research by offering high quality tissue with “flash-freeze” preservation from a wide range of normal and tumoral tissues. Providing front-line biospecimen procurement solutions in the field of cancer research, we bank and prospectively collect mirrored pairs of flash-frozen tissue + FFPE as well as other tissue pairs, pathologist-confirmed and sourced to meet your specific research needs.
Drive your cancer research further by purchasing flash-frozen human tumor tissue: our procurement services will cover a complete range of sourcing options, cancer types, tissue characteristics and formats covering a broad spectrum of anatomic sites and approved by the IRB.
Frozen Human Tissue Collection
Collection of non-fixed post-surgical tissue flash-frozen in liquid nitrogen (LN2) suits a variety of different research purposes representing a great resource for modern researchers. This method allows outstanding structural and biochemical preservation of the tissue and is the format of choice for the majority of downstream analysis.
Fresh frozen human tissues are collected under IRB approval and are prepared in strict accordance with our established processing protocol. Quality control by a certified pathologist is performed on all samples. Providing expertise in prospective collection services, Audubon Bioscience make available some of hard-to-procure items such as brain cancer and mitochondrial-related specimens.
Fresh Frozen Specimen Formats
Unless specifically indicated, standard fresh frozen tissue sections weigh between 0.5-1.0 grams. Frozen cancer tissues have the percent of tumor nuclei and tumor necrosis content verified by a pathologist.
We understand how quality of tissue fixation and preservation along with sample characteristics affects your downstream analysis and research performance. Tissues snap freezing is performed by submerging in liquid nitrogen (LN2) or in Optimal Cutting Temperature (OCT) media and stored at temperatures between -140°C and -180°C in the vapor-phase of LN2. Preserved within 15-30 minutes of collection, this format of tissue biospecimen will perfectly suit both prospective and retrospective collection as well as research-based custom protocols.
Snap-frozen tissues along with FFPE remain two most requested formats among modern researchers.
Laboratory Services for Frozen Tissue Samples
Understanding deviations in biospecimen collection, processing and storage is the key to data analysis and downstream operations. After your buy fresh frozen tissues and benefit from our high quality biospecimen procurement services, we can further support your study by assisting you with the downstream analytical process.
We provide turn-key additional testing - from extended pathology review, isolation from specialized tissues such as adipose or bone and finishing with flow cytometry of frozen tissue. Full array of dedicated services for the procurement of high-quality biospecimens includes sectioning and preparation of fresh frozen tissue sections.
Shipping of Fresh Frozen Tissues
From excision to storage and shipment, we guarantee high quality of our fresh frozen specimens by overseeing them with care and avoiding all possible intermediate thawing events.
Frozen samples are shipped on dry ice to avoid thawing and to ensure samples will be delivered at their best quality.
