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.

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.

Recombinant Therapeutic pAbs are Now Possible

2024-04-24T10:58:06-04:00January 20th, 2022|Webinars|

Polyclonal antibodies are popular research reagents for their high sensitivity and robust cross-platform performance. But few companies consider them viable for therapeutic applications as they are almost impossible to characterize. Additionally, they suffer from a lack of reproducibility and limited supply. Monoclonal antibodies (mAbs) can be reliably characterized and produced for therapeutic applications, but are more costly to discover and develop. Rapid Novor’s REpAb technology can overcome these limitations by capturing the sequences of the most abundant IgG in a pAb and enabling indefinite antibody production. Here we report the first successful conversion of a goat polyclonal antibody into a cocktail of recombinant mAbs using only the pAb protein sample.

Recombinant Antibodies: A New Generation Enabled by Protein Sequencing

Recombinant antibodies are artificially synthesized antibodies. Recombinant antibodies are generated from expression systems (e.g., E.coli, yeast, mammalian cell lines) via transfection with two separate plasmids encoding the amino acid sequences for the light and heavy chains, respectively. In order to recombinantly produce mAbs, the amino acid sequence of the light and heavy chains must be known. There are many ways to obtain the sequence of an antibody.

Non-Fungible Antibodies

Other than a paucity in widespread use, such efforts still do not address the main issue: the uniqueness of antibodies. Unlike currency, antibodies are non-fungible. To manufacture a replica of a specific antibody, we must first know its sequence. Sometimes, scientists may obtain the sequence through nucleotide sequencing means.
