The laboratory

The Munich Leukemia Laboratory (MLL) is one of the world's largest leukemia labs. Boasting state-of-art equipment and a bright and functional facility layout, MLL meets all the requirements of an innovative and modern workplace. With its adherence to the principles of consummate curiosity and its dedication to progress, the new-look MLL nevertheless remains true to its goal of facilitating access to targeted, efficient and timely therapy to patients worldwide.

  • 01/07 Sample receipt area
    Blood and bone marrow samples are received in the sample receipt area. They are unpacked, entered into our laboratory information and management system and labeled with an internal barcode. From here, each sample is allocated to a certain employee and equipment and is traceable in real time.

  • 02/07 Immunpophenotyping
    Immunophenotyping is a key to the diagnostic work-up of hematological neoplasias. It is used to corroborate diagnosis, classify diseases, assess prognosis and to quantify malignant cells over the course of treatment (minimal/measurable residual disease, MRD). Diagnostic application of the method is based on the characterization of antigen expression patterns of malignant cells and their discrimination from healthy cells. Learn more about Immunophenotyping.

  • 03/07 Molecular genetics
    Molecular genetics includes state-of-the-art methods for the identification of gene mutations with highest sensitivity. Genetic tumor profiling and determination of minimal residual disease (MRD) are elementary components of molecular genetics. Learn more about Molecular genetics.

  • 04/07 Cytomorphology
    The diagnostic work-up of hematological neoplasias is based on cytomorphology of blood and bone marrow smears. It is used to corroborate the diagnosis, classify diseases and assess prognoses over the course of treatment. In this regard, cytomorphology mainly involves the assessment of panoptical stains and a variety of cytohistochemical stains of blood and bone marrow smears. Learn more about Cytomorphology.

  • 05/07 Chromosome analysis
    Chromosome analysis is now considered an obligatory testing method for the diagnosis of hematological neoplasias. Its findings contribute to substantiating the diagnosis, although the prognostic significance that can be confirmed from the the karyotype of the malignat cells is far more important. Cancer-associated chromosomal aberrations occur only in malignant cells. These are acquired genetic mutations. Hence, the other cells in the body of a patient suffering from hematological neoplasias are cytogenetically normal. Learn more about chromosome analysis.

  • 06/07 Fluorescence in situ hybridizationg (FISH)
    Fluorescence in situ hybridizationg (FISH) uses fluorescent probes for the identification of known chromosomal or, rather, genetic aberrations in metaphase chromosomes or interphase nuclei. Learn more about FISH.

  • 07/07 Worklab
    In the newly designed worklab, visiting scientists from all over the worl are working on research projects in the field of leukemia diagnostics.

Our culture

Our mission

The focus of our work is the responsibility for patients with hematological neoplasms.

Our contribution is to provide comprehensive and personalized diagnostics with the shortest possible turnaround time.

The results of these diagnostics enable precise, individualized therapy with additional treatment options and improved chances of cure.

Our vision

We set standards in the diagnosis of hematological neoplasms through our own research and integration of global knowledge. To achieve this, we rely on our expertise, innovation and interdisciplinarity.

We are shaping the future of hematological diagnostics with state-of-the-art methods.

We are constantly working to further improve the chances of cure for hematologic neoplasms and are developing prevention concepts for this purpose.

Our values

We believe that extraordinary things emerge by blending knowledge, courage and responsibility.

In a world of constantly evolving, groundbreaking opportunities, our aim is to offer the best leukemia diagnostics at global level and to make it available to all patients.

  • We possess the knowledge to,
    accomplish extraordinary things.

    We are experts. Our findings are reliable and in line with the latest insight – thanks to diagnostics by an interdisciplinary team with a comprehensive scientific background and decades of experience as practicing hematologists, geneticists and bioinformatics specialists.

  • We have the courage
    to push boundaries.

    As committed go-getters, we are thirsty for knowledge, energetic and ambitious. We question the status quo, building on current standards to develop game-changing methods. State-of-the-art technology helps us to continue optimizing diagnostics.

  • We have the inner drive
    to seize responsibility.

    We are doctors, scientists, advisers, counsellors – and humans. At the heart of our work is the responsibility we accept for patients suffering from leukemia or lymphoma: We know that behind each sample, there is a personal story. This knowledge motivates us to proceed meticulously. Our optimized diagnoses based on an extensive spectrum of methods help to extend life expectancy with improved quality of life.

The team

We seek to comprehend what is not yet fully understood: how leukemia emerges, its interdependencies and complexity. As a large, interdisciplinary team of experienced doctors, biologists, bioinformatics specialists and medical technicians, we work to provide patients worldwide with more targeted and efficient treatments as quickly as possible. Our deployment of state-of-the-art methods and devices, continuous communication of test results between the various departments, as well as constant further training, ensure the speed and reliability of our diagnoses. Consistent sharing of test results and the steady expansion of staff knowledge guarantee reliable diagnostics. The team of excellently qualified staff members is therefore the nerve center at MLL.
