CompoZr® ZFN-modified breast cancer cell lines will accelerate drug discovery and enhance basic research
Sigma Life Science have expanded their CompoZr® Oncology Disease Model portfolio with the addition of breast cancer-specific knockout and knockin cell lines for drug discovery and research.
These modified epithelial cell lines are expected to provide researchers with a characterized and known genetic background for basic research and pathway analysis. They are supplied with isogenic parental cell lines to allow high throughput, cell-based screening for drug discovery, target validation and mechanistic studies. For more information, visit the company article page.
Important breast cancer genes — including Estrogen Receptor, PTEN and HER2 — have been targeted using Sigma Life Science's proprietary Zinc Finger Nuclease (ZFN) technology, to create stable and heritable genomic knockouts and to provide new cellular models of cancer. These modified human epithelial cell lines, including MCF10A, among others, offer researchers the complete knockout of disease-relevant target gene expression.
Supriya Shivakumar, Global Marketing Manager at Sigma Life Science, said, "These new knockout breast cancer cell lines, created using Sigma's ground-breaking CompoZr® ZFN technology, are expected to be ideal for high throughput screens to determine whether patient-relevant genetic alterations affect drug sensitivity or drug resistance. Researchers now have immediate access to high-quality knockout isogenic human cell lines, which should reduce the costs and labor required for basic research and drug discovery, and could accelerate the development of personalized medicine."

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Western BlottingWestern blotting equipment is used to transfer and identify specific proteins within a sample, reveal protein modifications, as well as give a semi-quantitative estimation of their concentration. Western blotting equipment includes all apparatus necessary to transfer proteins from gel to membrane and subsequent processing steps. Protein transfer can be performed by electroblotting with wet, semi-dry and dry transfer systems onto nitrocellulose and PVDF membranes. Blocking, washing and labeling of membranes follows, involving buffers, blocking reagents, blotting / incubation trays, labeling reagents, immunoblotting assays, antibodies and conjugates. Automated equipment for these steps is available to accelerate your lab workflow. Finally, detection and imaging of proteins can be conducted using gel documentation and imaging systems.

The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Biopharmaceutical AdvancesBiopharmaceutical advances follow the development of pharmaceuticals derived from biotechnology, also known as biotechnology medicines. Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.Clinical TrialsClinical Trials, an essential part of drug discovery process, assess the safety and effectiveness of a new medication or device in the pharmaceutical industry. Clinical Trials are a phased process (Phase 0, Phase I, Phase II, Phase III and Phase IV) which begins after initial preclinical testing.
