9B11 Is a Superior Clone against Top-cited Myc-tag Competitor


Posted by Tamar A. on May 20, 2020 3:15:00 AM

Biological research is about expanding knowledge, so it's not uncommon for scientists to become interested in studying proteins for which antibodies have not yet been developed. How then, can scientists pursue mechanistic studies of these novel or less-characterized proteins? Epitope tagging is a powerful tool for these protein studies and is used in myriad experimental applications. However, care must be taken not only in choice of epitope tag, but in selection and validation of antibodies.

Cell Process - How is cell proliferation quantified?


Posted by Tamar A. on Apr 22, 2020 3:00:00 AM

The production of new cells through cellular proliferation impacts the development, growth, and maintenance of all tissues in the body. This process must be tightly regulated, since uncontrolled cell division – as seen in various cancers – can lead to tumor formation and disrupt organ function. These broad implications for biological activities highlight the importance of understanding and accurately measuring cellular proliferation in a variety of contexts.

Cell Process: What is cell viability and how can it be measured?


Posted by Tamar A. on Apr 15, 2020 3:00:00 AM

The health of cells in culture is critical to the success of your experiments. Have you ever been excited about the experimental results of a knock-down, drug treatment, or culture condition, only to realize later that the effects are skewed due to the amount of cell death that occurred in your samples? Measuring and comparing cell viability in your assays is important, whether it’s the data you’re pursuing or an important control in your experiment.

Dual Staining Mouse CD8 and FoxP3 with Confidence


Posted by Tamar A. on Sep 25, 2019 3:15:00 AM

For decades, immunohistochemistry (IHC) has been a powerful technique for the investigation and visualization of cellular components in their native histological context. IHC has served as an important tool in medicine – enabling the diagnosis of complex pathological conditions – and in basic research to advance the understanding of key biological processes.

Visualize and Understand Protein Co-expression during EMT


Posted by Tamar A. on Aug 7, 2019 3:10:00 AM

Careful planning and the fine tuning of experimental protocols are key to ensuring clear, interpretable scientific results. This is especially true for immunohistochemistry (IHC) studies, where each step in the often multiday process – from tissue preparation to stain development – can significantly impact the final outcome and analysis. Often, the simultaneous examination of multiple antigens is required to address specific scientific questions, which further complicates IHC protocol development. A general understating of the steps necessary to optimize IHC for multiple targets is essential to achieve reliable results. So, what are these steps?
