Molecular biology holds the capacity to impact nearly every facet of drug research, development, and utilization.
The elementary molecular biology methods are used in basic research to cultivate bacterial cell lines for recombinant protein synthesis. Hence understanding the c0ncept behind target gene and method to the extraction of gene of interest (GOI) from the genome, clone GOI into an expression vector, create bacterial strain, identify positive clones, cultivate recombinant cells, and stimulate the synthesis of the target protein are crucial. Methods like Western blot, ELISA, and SDS-PAGE are employed to identify and measure the active recombinant protein. Many of the aspirants develop these skill while completing graduate degrees and are useful in R&D units across Biopharma sector. These techniques are often used in the biopharmaceutical development process to check the product quality.
Traditional methods of molecular biology use in drug discovery research involve tedious manual operations that do not offer sufficiently accurate and precise quantitation, or the desired turnaround time and sample throughput. In order to meet industrial standards and requirements, a fully automated, high throughput instrument for capillary electrophoresis (CE) protein separation and subsequent western blot analysis has been developed. This high throughput technology is being used in vaccine development, analysis of monoclonal antibody and peptide charge heterogeneity, biomarker detection, characterization of endogenous protein in cell lysates and industrial biopharmaceutical protein characterization. CE-based western blot are commonly for studies of medicinal proteins and vaccines. Molecular biologist should have this skill added to their continuous learning process. This technology at industrial level is being used as a best practice to quantitatively monitoring the clearance of a specific host cell proteins. Likewise, CE western technology has been more beneficial to evaluate contaminants of a biopharmaceutical Fusion-Fc protein during its purification process in comparison to traditional slab gel western blot. Such technologies are expedient to the quality by design (QbD) concept implementation in bipharma landscape, e.g. a biopharmaceutical protein in cell culture harvest samples was separated based on size using an automated CE western system to measure directly its two critical quality attributes namely a total protein expression or titer was measured using a primary antibody and a secondary antibody coupled with HRP to measure a total protein expression or titer and an HRP-conjugated primary antibody to measure manufacturing consistency in quantifying the relative distribution of the main protein isoforms. Therefore an innovative strategy based on automated CE western blot backs as a prospective analytical technique for sophisticated process control in the production of therapeutic proteins. [1] It is wise to advance the laboratory skill with CE based technologies. Promega, Agile Technologies, Lumex Instruments, Sebia, SCIEX, Helena Laboratories, Thermo Fisher Scientific, PerkinElmer, and BiOptic Inc. are the leading players in the capillary electrophoresis (CE) instruments market. To meet the needs of many industries, they provide a broad range of goods and solutions. To keep a competitive advantage in the market, they also frequently offer extensive customer support services and concentrate on ongoing product innovation. The market for capillary electrophoresis was estimated to be worth US$ 325.3 million in 2024 and is projected to grow at a compound annual growth rate (CAGR) of 4.3% from 2024 to 2031, reaching US$ 438.8 million.

Understanding the role of genetics in disease has become a central part of medical research while molecular biology based techniques are common tools used to study the functional genomics. Genomic analysis techniques such as Next-Generation Seqencing (NSG), microarray, RNA-Seqencing (RNA-Seq.), In-situ hybridization (ISH), quantitative real time polymerase chain reaction (qRT-PCR) are being used to look at the gene expression. When compare NSG with qPCR, qPCR can only i...
