What are FMO controls? 3 recommendations...
September 26, 2017
Keywords: flow cytometry experimental controls, fluorescence minus one staining control, FACS analysis tips and tricks, technical recommendations and complete downloadable ebook, immunology, cell biology products catalog, virtual event
There are 3 situations when an FMO control is highly recommended! The Fluorescence Minus One (FMO controls) are staining controls that contain all the antibodies of a panel minus 1 of them. It measures the spillover of all those other fluorophores in the channel of the missing antibody, and is used to identify and gate cells in the context of data spread due to the multiple fluorophores. It is a stronger negative control than the regular unstained control as it takes into account how the other stains in the panel impact the channel that is left out. Read on for technical tips and tricks when it comes to flow cytometry (FACS).

Download 2 Immunology Pathway PDFs Here!
September 15, 2017
Keywords: immunology IL-6 receptor pathway, IL-18 signaling pathway, interleukin, cytokine, cell-mediated immunity, inflammatory response regulation, immunology research useful diagram
Immunology is a complex and thoroughly researched topic today. Download your PDF study guides for IL-6 Receptor Pathway and IL-18 Signaling Pathway to reference at your convenience. The pathogenesis of many autoimmune diseases, multiple myeloma, and even prostate cancer are affected by the functions of IL6 and IL6R. Meanwhile, IL-18 is a proinflammatory cytokine which works with IL-12 to induce cell-mediated immunity following infection. IL-18 is able to induce severe inflammatory responses, suggesting it plays a role in various inflammatory disorders. Get your immunology posters, formatted in 8.5x11 inch (letter size).
Western Blot Tips and Tricks: Blocking Optimization
August 25, 2017
Keywords: Western Blot Blocking Optimization, wb membrane blocking troubleshooting, optimizing blocking and washing step of WB experiments
Do you Western Blot? Utilize our summary workflow for a standard Western Blot protocol, with necessary reagents for each step included! Following protein transfer, it is important to block the unreacted sites on the membrane using inert proteins and/or nonionic detergent to reduce levels of nonspecific protein binding during the assay. Blocking buffers should block all unreacted sites without disrupting target protein-membrane interactions or affect epitope availability. In this newsletter, learn the 3 key factors to consider when choosing an appropriate blocking agent for your specific Western Blot experiment!

Keywords: Breast Cancer Regulation by Stathmin pathway map, WNT signaling pathway free downloadable PDF file, cancer regulation through cell signaling pathways, study resource for cancer research, cancer related technical resource, biology pathway poster
The following 2 pathways are important for cancer research studies...
Stathmin is essential for the regulation of the cell cytoskeleton, which is required for numerous cell processes including regulating the cell cycle, cytoplasmic organization, cell division and cell motility.
WNT signaling has been identified for its role in carcinogenesis, in maintaining stem cells, and its function in embryonic development. Three WNT signaling pathways have been identified.
Which ELISA is for you?
July 28, 2017
Keywords: ELISA protocol, comparison table, technical tips, ELISA assay format, advantages of sandwich ELISA, indirect, direct, competitive immunoassay
Are you familiar with the multiple methods you could use to perform an ELISA? Among the standard assay formats, it is important to differentiate between the particular strategies that exist specifically for the detection step. An antigen could be captured to the plate by direct adsorption to the surface or through a pre-coated "capture" antibody, as in a sandwich ELISA. However, it is the detection step (direct or indirect detection) that largely determines the sensitivity of an ELISA. Read on to discover which ELISA is for you...
Protocol for Optimizing HIER Antigen Retrieval Conditions
July 14, 2017
Keywords: IHC optimization tips, antigen retrieval principle explanation, immunohistochemistry protocol optimize, how to perform HIER antigen retrieval for IHC experiment
If you are performing IHC experiments, you may need to optimize your antigen retrieval methods. Techniques generally fall into two main categories: protease-induced epitope retrieval (PIER) and heat-induced epitope retrieval (HIER). In general, HIER has a much higher success rate and is recommended over PIER methods. The protocol for HIER must be optimized for each sample tissue, fixation method, and antigen. This method is especially time-, temperature-, buffer-, and pH-sensitive, and the best condition must be determined empirically. Here is a step-wise protocol that may be helpful for your immunohistochemistry experiment.
The Why’s and How’s of Counting Cells for FACS
June 30, 2017
Keywords: Flow cytometry tips, counting cells principle explanation, FACS protocol cell count, how to count cells, hemocytometer
Counting cells before the staining procedure and the analysis/live sort is not up for debate! Cell numbers affect the staining quality, the FACS instrument reading, as well as the efficacy of any downstream assay, in case the cells are live sorted. Furthermore, cells are steadily lost during the staining procedure and it is therefore imperative that enough cells are available at the start of the experiment to compensate for the inevitable losses. There are various methods available for counting cells which are explained in this technical newsletter.
