CAR-iNKT Cells Targeting Clonal TCRVβ Chains as a Precise Strategy to Treat T Cell Lymphoma

2024-04-24T10:51:06-04:00June 16th, 2023|Case Studies|

With 22 functional T cell receptor (TCR)Vβ subunit families making up the normal T cell repertoire, signals from these cell surface receptors often determine the fate of normal cells. However, mutations in TCR signaling proteins are frequently associated with peripheral T cell lymphomas (TCLs), including adult T cell leukemia/lymphoma (ATL), which indicates a driving role for TCRs in TCL oncogenesis. As TCL and ATL are clonal in nature, tumour cells typically express a single TCRVβ subunit with no bias in the usage of TCRVβ subunit families. Consequently, targeting the specific TCRVβ subunit presents a promising therapeutic approach that is highly selective and tumour-specific.

Technologies for Antibody Discovery and Generation

2024-05-06T11:49:48-04:00December 23rd, 2022|Articles|

The great debate on the use of in vivo versus in vitro sources and strategies for antibody discovery and generation continues to thrive among antibody research groups. On one side of the debate is the argument for non-animal-derived antibodies due to the technical advancements of current in vitro technologies, and the moral obligation to reduce animal usage. On the other side of the debate is the counterargument for animal-derived antibodies due to their better performance in affinity, specificity, and reduced immunogenicity risk.

Resistance to Autosomal Dominant Alzheimer’s Disease in an APOE3 Christchurch Homozygote

2024-04-24T10:43:19-04:00October 21st, 2022|Case Studies|

De novo protein sequencing provided the research team with insurance by securing the complete amino acid sequence of a therapeutic mAb candidate for ADAD. This mass spectrometry-based protein sequencing technique can be used to obtain the sequence information of any antibody or protein for biomarker discovery, characterization, and validation. Access to this structural information only broadens our understanding of disease pathogenesis and fosters the development of innovative therapeutic or preventative treatments.

Generation and Diversification of Recombinant Monoclonal Antibodies

2024-04-29T13:20:43-04:00April 22nd, 2022|Case Studies|

Monoclonal antibodies are essential reagents and research tools. They are commonly generated and produced in hybridoma cells and are expected to be highly consistent. However, the instability and fragility of hybridoma cells can cause unwanted mutations, additional chains, and permanent loss of important antibodies. On the other hand, the lack of standardization validation for commercial antibodies often keeps researchers in the dark leading to the reproducibility crisis.

Next Generation Protein Sequencing in Veterinary Medicine and Industry

2024-04-24T10:44:32-04:00December 3rd, 2021|Whitepapers|

Since 2006, the One Health Initiative (OHI)’s goal has been to demonstrate the inextricable link between humans, animals, and the environment. Certainly, the current global pandemic is a great testament to the ties between climate change, humans, and animals that OHI has been working to highlight. The rise of other zoonotic diseases (e.g., Hendra, and Nipah viruses) not only directly affect humans through disease transmission but may also result in deep impacts to the food supply
