LC-MS analysis for advanced therapies

The challenges of analyzing process-related impurities facing developers of advanced therapies and bacteriophages are unique and remarkably complex.

Now, Alphalyse is delivering a new era of process-related impurity analysis based on mass spectrometry (LC-MS). Our unique solutions have finally made LC-MS analysis easy to access - and it is fast becoming the 'must-have' technique for cell & gene therapy analysis.

 

Featured webinar

LC-MS HCP assay validation and GMP release testing for complex samples

An MS-based assay is ideal when the complexity of your therapeutic makes it challenging to find or develop an adequate ELISA. The focus in this webinar is on the analytical methods for characterizing HCPs, residual proteins, viral vector proteins, and other proteins in highly complex products - and use the data for release testing.

How an LC-MS assay can help you

Bringing absolute clarity to protein impurity analysis

Within weeks, one assay unlocks the identity and quantity of all proteins irrespective of their source, even if they originate from several different host species. The data allows you to understand and control the purification process and ensure consistent product quality, purity, regulatory compliance, and patient safety.

The LC-MS assay is applicable for products based on lentivirus, retrovirus, adenovirus (oncolytic virus), adeno-associated virus (AAV) vectors, bacteriophages (phage therapy), and more.

Assess the presence and potential impact of process-related impurities on your product. Identify and quantify residual proteins at each stage of the downstream process to ensure all impurities of concern can be efficiently removed.

Gain a thorough understanding of your biotherapeutic product. Optimize your process design and ensure that your product achieves all safety, purity, and potency attributes required by regulatory authorities.

FAQ

Regulatory standards and clinical administration require thorough documentation of quality attributes pertaining to drug product identity, purity, potency, stability, and safety. However, the high complexity of C&GTs poses a considerable challenge for impurity and product characterization strategies.

Unlike traditional biologics, which are typically manufactured by expressing one recombinant protein in a single cell line, advanced therapies contain highly heterogeneous protein mixtures from multiple sources and organisms. Traditional biologics also have well-defined manufacturing processes supported by established analytical methods, whereas the manufacturing processes for cell & gene therapies are often still in development.

Improved analytical tools, such as mass spectrometry (LC-MS), ensure process consistency and quality and meet regulatory requirements for product release and characterization.
