Durviz, intermediary between Mission Bio and the Josep Carreras center


Durviz acts as an intermediary in the current collaboration between Mission Bio and the Josep Carreras Research Center. A job that makes us proud because it is a new acknowledgment of the work that we have been developing for years in the health research sector.


Durviz, intermediary between Mission Bio and the Josep Carreras center

Durviz has been key in the collaboration established by Mission Bio and the Josep Carreras Research Center in Barcelona. A space in which fundamental work will be carried out that will be a boost to our trajectory and a challenge for the future of cancer research

Mission Bio: What is it?

Mission Bio is the name of a US company dedicated to performing high-throughput single-cell DNA and multi-omic analyses. Its main goal is to help researchers and clinicians unlock single-cell biology to enable the discovery, development, and delivery of precision medicine.

It should be noted, at this point, that through its centers of excellence, Mission Bio partners with leaders within the solid tumor and hematologic malignancy research communities. All this with the aim of continuing to build and refine the functionality of Tapestri, the only equipment available on the market capable of simultaneously analyzing DNA and other analytes such as cell surface proteins at the level of a single cell, through its exclusive two-step microfluidic technology.

Its international development and search for alliances has led it to create the first and only Center of Excellence in Europe, located at the Josep Carreras Leukemia Research Institute. A space that will be directed by the renowned doctor Manel Esteller.


Josep Carreras Research Center

The Josep Carreras Research Institute is the first European research center specializing in leukemia and other blood cancers.

Its main research objective is the identification of new therapeutic targets; as well as in the development of more precise and less aggressive treatments by understanding the origin and development of leukemia and other blood cancers.

Manuel Esteller, director of the Josep Carreras Institute, is the author of more than six hundred original publications in peer-reviewed scientific journals. At the same time he is editor-in-chief of “Epigenetics”, and a member of the editorial board of Genome Research. Also, last year, he co-authored a paper in Experimental Hematology. This discussed the benefits of single cell analysis to characterize heterogeneity. Also of the clonal evolution of blood cell subpopulations in myeloid and lymphoid cancers. Some results that can improve the diagnosis of patients, risk stratification and the prescription of targeted therapies.

As Mission Bio’s second single-cell Tapestri Center of Excellence, and the first in Europe, the Josep Carreras Institute will inform academic and industry best practices. It will do this using single cell and multi-omic DNA sequencing in haematological malignancy research. At the same time, it will launch a new program in breast cancer.


The Josep Carreras Institute has long been a benchmark in the development of single-cell analysis and launched a specialized unit in 2021.


The partnership with Mission Bio will boost the Josep Carreras Institute’s application of single-cell DNA sequencing to investigate disease progression. Also its therapeutic resistance and measurable residual disease (MRD) both in blood cancers and in its innovative breast cancer research program.


Durviz as intermediary with Mission Bio

Durviz has been working hand in hand with Mission Bio and the Josep Carreras Foundation for years. And he will be responsible for supplying everything needed to carry out the investigations with Tapestri, Mission Bio’s revolutionary team. A group with which clonal mosaicism and neoplastic transition, clonal evolution, can be questioned. But also metastatic spread with its ability to co-detect SNV and CNV at the single cell level in a scalable manner.

This is very important since it is a tool that allows us to understand resistance to diseases. So users can detect rare emerging clones early. And do it with reliable and sensitive measures of loss of heterozygosity. Which helps them understand how driver mutations are acquired over time that can allow tumor escape and metastasis.

It is also critical for developing single-cell multi-omics analysis. This is of growing importance in oncology precision medicine as it sheds light on the clonal structure of tumors to guide combination therapeutic development and personalized treatment.

A job in which we at Durviz are delighted to participate.

Rapid COVID 19 test from blood, serum or plasma

If you need to do a rapid COVID 19 detection test from blood, serum or plasma samples, at Durviz we have the product you need. It is an exclusive proposal for use in laboratories


Rapid COVID 19 test from blood, serum or plasma

The rapid test that we propose at Durviz is a lateral flow chromatographic immunoassay that allows the qualitative detection of IgG and IgM antibodies against 2019-nCoV. An action that it is capable of carrying out in human blood, serum, plasma or also in a blood sample with a lancet.

This product uses immunochromatography as a detection technique. These types of tests are commonly used for medical diagnosis both for home tests and for use in the laboratory. Hence, it is one of the most requested media by professionals at the present time.

And it is that immunochromatography is one of the most widely used immunodiagnostic techniques today. Its main attractions are: the simplicity and speed of the tests that use this proposal. Hence, with the current need for diagnoses due to the COVID 19 pandemic, there are more and more applications of this technique in the field of tests. Especially since it does not need reagents or additional instrumentation for its operation. Something that does occur in other similar methodologies that are applied to the clinical field.


Advantages of the rapid COVID 19 test

The main advantages of this product are the following:

  • It is presented in a strip format, in which the test sample flows along a solid substrate through capillary action.
  • This is a combined antibody test that can provide information on the stage of infection of the person being tested. And it is that the detection of COVID-19 IgM antibodies tends to indicate a recent exposure to COVID-19, while the detection of COVID-19 IgG antibodies indicate a later stage of infection.
  • The test contains anti-human IgM and anti-human IgG as capture reagent, 2019-nCoV antigen as detection reagent. An IgG reagent is used in the control line system.
  • It is a product for exclusive use in laboratories.


To all this must be added, in addition, that IgM provides the first line of defense during viral infections, followed by the generation of adaptive responses of high anity of IgG for long-term immunity and immunological memory.


COVID 19 Rapid Test Features

The main features of the COVID 19 rapid test are as follows:

  • Testing should be done immediately after samples have been collected.
  • Serum and plasma samples can be stored at 2-8 ° C for up to 7 days. For long-term storage, serum / plasma samples should be kept below -20 ° C. Whole blood collected by venipuncture should be stored at 2-8 ° C if testing will be performed within 2 days of collection.
  • Negative results do not rule out SARS-CoV-2 infection. This should be taken into account particularly in those people who have been in contact with the virus. A follow-up test with a molecular diagnosis should be considered to rule out infection in these individuals.
  • Results of antibody tests should not be used as the sole basis for making a diagnosis. Neither to exclude a SARS-CoV-2 infection or to report infection status.


So, if you are looking for a system that allows you to perform a rapid test to detect the presence of COVId 19 from blood, serum or plasma, do not hesitate and visit our website. You can buy both this product that we have reviewed in this article, as well as many other accessories. Everything so that you can acquire the best and most reliable results in your laboratory.
