Sample fixation is a required and crucial step for every successful IHC/ICC experiment. Choosing which fixing solution to use depends on your sample type and antigen. Since there is no standard fixing solution for all samples, we recommend testing to determine which specific type of solution will be most appropriate and effective for antigen immobilization in your sample. Read on to learn more about IHC and ICC fixation.

Cancer stem cells (CSCs), also known as tumor-initiating cells (TICs), are a subpopulation of cancer cells that possess the self-renewal and multi/pluripotency properties similar to that of normal stem cells. They have been identified to be tumorigenic and linked with inducing metastasis. Several molecular signaling pathways are associated with governing stem cell homeostasis. Normally, these pathways are highly regulated. However, an increasing number of these signaling pathways have been discovered to become dysfunctional in CSCs, which include the JAK/STAT, Hedgehog, Wnt, Notch, NF-κB, PI3K and PTEN signaling pathways. In certain cases, cross-talk between different pathways contribute to CSC population maintenance. Download the pathway map poster to learn more.
Taking place in San Antonio, Texas, March 11–15, 2018, the SOT Annual Meeting will feature 2,000+ presenters and 170 Scientific Sessions. Over 6,500 attendees are anticipated for the event!

In the lab, researchers invest time and effort to optimize the sample preparation and sample staining processes of IHC. When successful, the results produce a strong and specific signal. However, how do we know the results have been interpreted correctly? When designing your IHC experiment, it is crucial to include positive and negative controls. The controls will help verify whether or not the IHC staining results observed are accurate and valid while exposing experimental artefacts. Read on to find out the 6 established controls for IHC!

ELISA is a convenient and simple method to quantitatively or qualitatively detect peptides, proteins, antibodies, and hormones in samples, rendering it as one of the most widely used immunoassays. Despite the many advantages of conducting ELISA, there are some mistakes that could quickly turn your ELISA experiment sour.

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).

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).
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!
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.
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...
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.
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.
Optimizing your ELISA immunoassay can be a long and tedious process. Fortunately, using checkboard titration could help you optimize your ELISA assay more quickly, efficiently, and accurately. Here is a how-to-guide for utilizing this method in your next ELISA protocol.
Antigen retrieval is often necessary when performing IHC experiments. Here are some key points to know about HIER and PIER methods of antigen retrieval. This protocol step needs to be optimized for every antigen of interest.

The purpose of using a secondary antibody is to amplify the primary antibody and antigen interactions signals. If you need secondary antibodies for your experiment, then you probably know there are many elements to consider when choosing the right antibody such as species reactivity. Dr. Booster has a few guidelines for you to keep in mind about secondary antibodies. Be sure to take a look and confirm everything is good to go.
With today's selection of fluorochromes, FACS panels can become quite complex. Working with multiple colors and antibodies will require the appropriate experimental controls in order to properly interpret the data results. Check to make sure you have included all the appropriate controls before your cell sorting experiment! This convenient mini guide to FACS staining controls by Dr. Booster should be a helpful reference tool.
Are you preparing for a FACS experiment? Here’s a 10 point checklist to help you get ready prior to cell sorting. We suggest going through this checklist beforehand, as your cell sorting process may go more quickly and efficiently if you read the following tips.
