Formalin-Fixed, Paraffin-Embedded Tissues (FFPE)

Our human tissue specimens are offered in several formats to meet the needs of biomedical research:

Individual Tissue Specimens

• Individual FFPE tissue samples, diseased or normal.

Matched Tissues and Fluids

• FFPE diseased/tumor or normal tissues with matched blood products or biofluids.

Matched Tissue Pairs

• FFPE diseased/tumor and normal adjacent tissues (NAT) from a single donor.
• Paired FFPE and fresh frozen tissues (diseased/tumor or normal) from a single donor.
• FFPE diseased/tumor and metastatic tissue samples from a single donor.

Quad Tissue Sets

• FFPE and fresh frozen tumor and normal adjacent tissue samples from one patient

Tissues are fixed for 18 – 24 hours at room temperature, then embedded in IHC-grade paraffin.

• Standard sample size is 1 x 1 x 0.5cm, but can vary based on the nature of the disease or tissue type.
• The fixation agent and embedding media can be customized upon request.

FFPE tissues are stored at room temperature.

Standard-sized FFPE tissues can yield at least 500 x 4-5µm cuts.

FFPE tissue specimens are collected under a strict Standard Operating Procedure (SOP). Quality Control (H&E staining) is performed on 100% of collected FFPE tissue samples.

Unless indicated (for special cases, or custom collections) all FFPE tumor tissues have at least 60% tumor content.

From excision to storage to shipment, each specimen is handled with care and precision to ensure that the highest quality specimens are delivered to our customers.
