Autism biomarkers
New research has indicated that mass spectrometry (MS) could be used in the diagnosis and, potentially, in the prognosis of autism spectrum disorders (ASD).
New research has indicated that mass spectrometry (MS) could be used in the diagnosis and, potentially, in the prognosis of autism spectrum disorders (ASD).1 Currently, autism is diagnosed based on clinical observation.
A team of scientists have investigated the potential use of MS and suggest that particular protein patterns or biomarkers can be used in the detection of ASD. MS techniques were used in the protein profiling of the blood plasma of children with such disorders in order to identify peptides that could be used as biomarkers. These results were then compared with a control group. They found that three differentially expressed peptides with m/z values of 2020±1, 1864±1 and 1978±1 Da were significantly changed when compared with the control results.
The study concluded that these results allow for a reliable blood-based diagnostic tool.

AI and GenAI Applications to Help Optimize Purification and Yield of Antibodies From Plasma
October 31st 2024Deriving antibodies from plasma products involves several steps, typically starting from the collection of plasma and ending with the purification of the desired antibodies. These are: plasma collection; plasma pooling; fractionation; antibody purification; concentration and formulation; quality control; and packaging and storage. This process results in a purified antibody product that can be used for therapeutic purposes, diagnostic tests, or research. Each step is critical to ensure the safety, efficacy, and quality of the final product. Applications of AI/GenAI in many of these steps can significantly help in the optimization of purification and yield of the desired antibodies. Some specific use-cases are: selecting and optimizing plasma units for optimized plasma pooling; GenAI solution for enterprise search on internal knowledge portal; analysing and optimizing production batch profitability, inventory, yields; monitoring production batch key performance indicators for outlier identification; monitoring production equipment to predict maintenance events; and reducing quality control laboratory testing turnaround time.
