Press Release

July 30, 2019 – Des Plaines, IL – We are pleased to inform you that MBL International has sold our stake in BION Enterprises to the AESKU Group effective July 30, 2019.  BION Enterprises manufactured IFA Slides and component kits and handled commercial transactions for our In Vitro Diagnostics line of products. Changes to MBL’s business strategy, as well as changing market dynamics, drove our decision to divest the IFA business.

MBL International will now focus our efforts on providing solutions for researchers working in immunology, immune-oncology, oncology, and autoimmune disease areas. As a JSR Life Sciences Company, MBLI is committed to improve the probability of success, decrease timelines, and increase the efficacy of biologics-based therapies for the benefit of patients.

We appreciate your business over the years and look forward to our continued partnership in the years to come.

  While, in theory, using antibodies against Fc Receptors (FcRs) is the best way to eliminate unwanted signals mediated by FcR binding, you may not always have a well-optimized antibody pool against FcRs sitting right in front of you for your experiment. Furthermore, such a blocker may not be applicable when you have one of the FcRs, such as CD16, CD32 or CD64 to measure in your channel. In this blog, we share an “old school” way of blocking by just using a serum that is routinely available in most labs. Read more

• New tetramer for vaccine research targeting Tuberculosis and Ag85B specific T-cells

  Tue, 23 Jul 2019 17:00:00 GMTBy: bindi.doshi@mblintl.com (Bindi M. Doshi, PhD)

  Tuberculosis (TB) is caused by the Mycobacterium tuberculosis and usually targets the lungs.  This disease is spread when an infected person sneezes or coughs, thereby releasing small droplets into the air and passing to a new individual. When left untreated, death can occur. Thankfully, there is a vaccine for TB called Bacille Calmette-Gurin (BCG) and is often given to young children.  This vaccine has been shown to last 15 years. There is some doubt about the efficacy of the BCG vaccine in adult pulmonary TB1,2.  For this reason, more research needs to be done to provide a safe and effective TB vaccine for adults.
  Antigen (Ag) 85 is gaining interest among vaccine development research.  Ag85 is preserved in Mycobacterium and allows bacteria to evade the host immune response by preventing mechanisms involved in terminating the infection3.  Research continues to uncover exactly how Mycobacterium tuberculosis persists and remains in an infected person while evading the immune system.  New advances in immunology are giving researchers a greater picture for how the immune response is manipulated by this bacteria.  It is clear that with greater understanding of how the human immune response system functions and how different infections manipulate this system, that targeted therapies, including vaccines, can be developed to combat the infection successfully.
  MBL International is pleased to announce the launch of our new tetramer targeted to Ag85B-specific T cells for murine studies. As always, our team is on hand for any question or request that you may have.

• Why protein phosphorylation is crucial in disease research

  Thu, 13 Jun 2019 17:00:00 GMTBy: bindi.doshi@mblintl.com (Bindi M. Doshi, PhD)

  Protein phosphorylation is quintessential for specific pathways to function.  This function can be influenced by internal or external factors.  It is a reversible action with the involvement of kinases and phosphatases1.  This activity is crucial in the cell cycle, apoptosis, and signal transduction pathways.  If a protein is phosphorylated or dephosphorylated when it shouldn’t be, there can be severe disruptions to the cellular pathway.  At times, the phosphorylation state can be the cause of a disease.  This has been found in degenerative diseases, cancers, and various pathways involving the immune system2.  For instance, kinase inhibitors have been successful in cancer treatments. 
  Enzymes control phosphorylation.  Kinases function to add phosphate groups to proteins and phosphatases function to remove phosphates.  Typically, phosphorylation occurs on serine, threonine, or tyrosine residues. This process can be very quick or it can take many hours. It results in a conformational change which either activates or inactivates protein activity. Read more
