The biobank of the Parc de Salut Mar (MARBiobanc) is a public, non-for-profit facility which stores various collections of biological samples available to the whole scientific community. It is organized as a technical unit with regards to quality, order and destination.

It has restricted access facilities which are equipped with the security control mechanisms necessary to ensure the correct storage of the biological samples, their confidentiality and their traceability in accordance with all the Spanish ethical and legal regulations.

The Biobank Service is certified by AENOR to ISO 9001:2015.

Available human biospecimen collections

• DNA bank for cardiovascular diseases

• Cerebral infarction (ictus) sample bank

• FORTIAM, acute myocardial infarction sample collection

• DNA bank for oncological diseases

• Bank of samples from influenza A (H1N1) patients

• Bank of lung disease samples (Lung Biobank Platform)

• Hematological malignancies bank

• Left over diagnose sample bank

• Tumoroids collection from human colorectal cancer

Research line collections

• Three new research line collections have been added to the Biobank facility to be managed under biobank standards.


There were 17 active services in 2018.

There were 7,276 new donors in 2018.

The Biobank is subscribed to the Biobanks European Quality Control Program, organized by the IBBL (Integrated Biobank of Luxembourg).

MARBiobanc is the first biobank in Spain to implement an evaluation as a way of controlling samples transferred to clinical trials and their future uses.

In addition, MARBiobanc reviews all the agreements with the pharmaceutical industry to prevent surpluses being used for unspecified research. This special and urgent evaluation system guarantees the necessary speed and control of samples used in clinical trials.

The Reference Laboratory of Catalonia (Laboratori de Referència de Catalunya-LCR) has been included in the MARBiobanc as a new node. This new node includes all residual samples obtained at the phlebotomy department.

Microdissector Laser (microscopy area)

The ArcturusXT™ microdissection system offers a combination of infrared (IR) laser capture using standard slides, or a combination of both infrared and ultraviolet (IR and UV) laser, using polyethylene naphthalate (PEN) membrane slides laser enabled.

The instrument has a proprietary combination of a gentle IR laser and a powerful UV laser that work in conjunction to efficiently isolate cells without changing morphology or integrity of the biological content. The IR laser helps to capture the cells of interest, and the UV laser microdissects the captured cells. This is done without affecting the morphology of the cells, and allows for visual inspection of the remaining specimen to help ensure the quality of the sample collected. A wide-slide stage format is available for neurobiology researchers working with very large sections of brain tissue. The petri dish stage insert has opened the door for live-cell microdissection applications such as stem cell research and other rare-cell isolations.

The LCM technique can be used on formalin-fixed, paraffin-embedded (FFPE) sections, allowing the use of archival pathological material. In addition, frozen sections of tissue and cytological specimens are also suitable for laser microdissection. The technique causes no apparent alteration to the morphology of the chosen cells, which can be directly visualized after microdissection.

Key features

• Dual laser system-enables a wide range of applications ranging from single-cell isolation to large biopsy extractions.

• IR laser capture microdissection preserves morphology of isolated samples and integrity of biological material for downstream applications.

• Software enables rapid isolation of specific cells in five simple steps, provides quality control feature that allows users to visualize collected sample.

• Flexible sample prep-wide range of slide types and sample preparation formats supported.
