MYstik™, plug&play mouse isotyping kit

SYnAbs Mouse Immunoglobulin Easy Isotyping Kit or a.k.a. "MYstik™" provides a rapid and easy method (DOT technology) to characterize mouse monoclonal antibody isotypes in cell culture supernatants or purified antibodies preparations. This Plug&Play kit includes ready-to-use reagents necessary to analyze 24 samples in less than 1h30. Buffer solutions are color-coded to simplify pipetting steps.

The method is based upon robust EIA enzyme immunoassay technique:  SYnAbs unique rat anti-mouse monoclonals are highly specific to each of the common light and heavy chains of mouse species and can discriminate between IgG1, IgG2a, IgG2b, IgG3, IgM, IgA, IgE, kappa chain and lambda chain. Samples are placed on the strip without any predilution. If desired isotype mAb is present, it will bind to rat mAb by affinity. Note that only specific mAb and none the irrelevant molecules will bind. That counts for the specificity of the test. The second mAb is then added, this one conjugated with the enzyme. A colorgenic enzyme substrate is added. The interaction between the substrate and the captured enzyme generates visible color or dot.

SYnAbs/RD Biotech unique expertise in CAR-T cells

Numbers speak for themselves : 83% of the 63 evaluable children who received tisagenlecleucel in phase 2 trial had complete elimination of malignant cells in just 3 months, while no other therapeutic option are available.

For those of you living on the moon for the last 5 years, this is the « miracle cure » of cancer : CAR-T adoptive cell therapy. The approval of Novartis’ Kymriah made headlines in August this year as the first gene-edited cell therapy for cancer to be approved by FDA. Probably the first of a long series.

RD-Biotech/SynAbs/Diaclone association has recently entered the field by providing a unique one-stop-shop solution for biotech players developing the mentioned approach.

RD Biotech starts with the expression of recombinant cancer antigen in order to specifically generate the adequate mouse monoclonal antibody against it. Thanks to molecular platform, the sequencing of VH and VL regions of this last structure allows us to create an extracellular single-chain variable fragment (scFv), first component of Chimeric antigen receptors, or CARs.

 Following the collection of a patient's T cells by leukapheresis, the cells are genetically engineered by RD-Biotech through inactivated lentivirus particles containing the coding sequence for the CAR. In fact, lentivirus are used for the transfection of activated T cells, introducing the complete pattern of CAR : scFv derived from an antibody, joined to a spacer peptide and a transmembrane domain, which is further linked to the intracellular T cell signaling domains of the T cell receptor : CAR T cells have just been born right before our eyes !

To ensure that the CAR-T cell is well activated, Diaclone launches its specific interferon gamma ELISpot test assay attesting that the CAR-T combines the specificity of an antibody for CD proteins, with the cytotoxic and memory functions of T cells.

Since we’re speaking of a mouse ScFv, the use of the rat as a host animal allows better immunization and thereby greater diversity of monoclonal antibodies against regions that would not be immunogenic if the mouse was used. Drawing on its expertise in secondary monoclonal antibodies, SynAbs is now part of cell therapy game by generating rat monoclonal antibodies against mouse CAR-T.

Thanks to this new available tool, our partners are now able to select specific transfected CAR-T populations on flow cytometry platform !

 Regarding therapeutic applications, RD-Biotech will then loop the loop, offering to its worldwide customers its expertise to humanize the generated ScFv, providing a better tolerance of the CAR-T for human body meanwhile maintaining the high functionality provided by the rat immune repertoire !

The best of both worlds for better antibodies tools in cell therapy!

SYnAbs, from UCL benches to Singapore

November 24, 2017 12:00 AM,

Guy Dellicour, L’echo

The innovative products of the young start-up will be distributed in Singapore, booming biotechnology hub in Asia. Two years after its creation, SynAbs has already doubled its turnover and already achieved financial balance. 

For scientists, Gosselies is not known only for its airport but especially for its many innovative companies in biotechnology. Among these, SynAbs has specialized itself in the manufacturing, for its customers, of custom monoclonal antibodies, or on the basis of a catalog of more than 1,000 references. It is the only private company of this type in Belgium and the world market is shared between 300 actors.

Put its bet on the guinea pig species

Antibodies are widely used as diagnostic tools for allergies, for pregnancy tests, in diabetes screening or in development for Parkinson's or Alzheimer's diseases. They are also increasingly used as therapeutic solutions, especially in immunotherapy.

Traditional antibody production techniques for R&D and In Vitro Diagnostic applications have been increased to more than 70% by the mouse. However, this platform does not always make it possible to obtain an effective product against certain toxins, which remain imperceptible by the immune system of these animals.

To overcome these intrinsic limitations, SynAbs has developed a unique technique for producing antibodies from rats and guinea pigs, genetically further distant from humans. Unlike insulin in mice, rats and rabbits, which is identical to human insulin, guinea pig insulin is unique.

A billion-dollar market

The potential for the development of an antibody against the different glycemic hormones involved in diabetes (a huge market) is even higher. "This animal is finally an optimum in terms of cost-effectiveness and space utilization," says Didier Argentin, "Our expertise in monoclonal antibodies to rats and guinea pigs is almost unique in the world. We have worked on this during more than an entire year', he confesses with delight.

The market for monoclonal antibodies in R&D and IVD is estimated as $ 1 billion.

"Our goal is to capture half of the rabbit monoclonal antibody market, with an annual turnover of around €50 million, which will require new organization and financial means." 

SynAbs can certainly count for its future development on its French shareholder Biotech Investissement (which holds a 75% stake) as well as other public and private financial investors.

The company currently employs 7 senior scientific collaborators and is expected to exceed a turnover of 700,000 euros in 2017 (doubled in 2 years), of whose more than 50% is generated on the international scene.

In association with Coris Bioconcept, SynAbs has just won the Walloon project dedicated to the specific detection of bacteria resistance to antibiotics, with more than 1.5 million euros. Its presence abroad has also recently been strengthened by the signing of a distribution agreement in Singapore, the Asian biotechnology hub. Growth is just beginning.
