B-cells (or B lymphocytes) are a category of white blood cells that express clonally diverse B-cell receptors (BCRs) which recognize specific antigenic epitopes. B lymphocytes also play a critical role in the adaptive humoral immune system by producing and secreting antigen-specific immunoglobulin (Ig) (generally referred as antibodies).

The common problem for all fluorescence-based cell detection methods is the cells’ natural fluorescence. Cellular autofluorescence is due to the presence of various biological structures, such as collagen, elastin, NADPH, flavins, mitochondria, and lysosomes, which usually absorb in UV to blue range (355-488 nm) and emit in the blue to green range (350-550 nm). Therefore, autofluorescence interferes with analysis by reducing signal sensitivity and resolution of fluorochromes that operate in that range – FITC, GFP, and Pacific Blue to name a few.
Allergies are when the body’s immune system has a hypersensitive reaction towards innocuous substances called allergens. Common allergens include dust mites, pollen, mold, food, and animal dander, which could trigger allergic disorders such as allergic asthma, hay fever, allergic rhinitis, anaphylaxis, allergic conjunctivitis, and contact dermatitis. When a susceptible individual is newly exposed to an allergen, the immune system undergoes allergic sensitization.
The ELISA is one of the most commonly performed bioassays that produces qualitative, semi-quantitative, and quantitative data. In order to obtain quantitative ELISA data, constructing the ELISA standard curve is an important and crucial process to estimate the target protein concentrations for your samples.
In 2018, more than 266,000 women will be diagnosed with breast cancer in the United States. According to the American Cancer Society, over 40,000 women will die from breast cancer this year. It is the second leading cause of cancer death in American women. Breast cancer is the most common cancer in women in the US and worldwide, regardless of race or ethnicity.
Boster now offers 1300+ rabbit monoclonal antibodies validated for many applications including flow cytometry, IP, IF, IHC, ICC, WB, and ELISAs. The rabbit immune system has historically been useful for generating a larger diversity of high affinity antibodies, including phospho-peptides, carbohydrates, and immunogens not immunogenic in mouse.
The ELISA (enzyme-linked immunosorbent assay) is recognized by scientists for its many advantages. The assay is convenient, quick, and simple to execute. ELISA’s versatility to detect peptides, proteins, antibodies, and hormones, and its ability to generate quantitative and qualitative data make it one of the most popular and powerful immunoassays available.
T cells are a category of lymphocytes that differ from other lymphocytes because of the unique T cell receptor (TCR) present on the cell surface. Together with co-receptors (CD4 for helper T cells and CD8 for cytotoxic T cells), the TCR enables T cells to detect and react to peptide antigens, which are pathogens digested by antigen presenting cells (APCs) and displayed on major histocompatibility complex (MHC) molecules.
September is World Alzheimer’s Month, an international campaign to raise dementia awareness and challenge stigma, and the purple ribbon is the chosen color to represent awareness for Alzheimer’s disease. The impact of this campaign is growing, but the stigmatization and misinformation that surrounds dementia remains a global issue.

CTLA4 (cytotoxic T-lymphocyte–associated antigen 4, aka CD152) is a transmembrane protein member of the immunoglobin superfamily. This protein receptor plays a key role in downregulating immune responses (e.g. inhibit T-cell activation). Its expression relies on the stimulation of TCR and the binding between CD28 and B7 (B7-1/CD80 & B7-2/CD86), which both promote T-cell activation.
This Saturday, July 28th, is World Hepatitis Day, an annual international awareness event for the over half a billion people globally affected by hepatitis. World Hepatitis Day is one of the eight official WHO health days that is supported by many organizations such as the World Hepatitis Alliance, HHS, and CDC.
First described in 1979, the technique of western blotting has since become one of the most commonly used analytical methods in life science research. Just last week, we received a few questions from confused researchers about weird band sizes in their western blot results.
Our team of experts is dedicated to provide services that are tailored to your needs and specifications. We are committed to being transparent about the timeline, the costs involved, and the progress of your project. A project manager will be assigned to your project to answer all your questions.
At Boster, one common question we get from researchers is, “How do I prepare the ELISA standard?” We’re glad you asked because proper construction of the standard curve is the very first step for every ELISA experiment. The standard curve can help confirm that the quality of the kit and the operation procedures are acceptable for further steps.

Caspases are a family of cysteine proteases that respond in succession when activated by apoptosis stimuli, leading to proteolysis, cell disassembly, and apoptosis. The caspase cascade can be triggered by stimuli from the cell surface or the mitochondria. Pro-apoptotic stimuli, such as TNF (Tumor Necrosis Factor), FasL (Fas Ligand), GRB (Growth Factor Receptor-Bound Protein), Granzyme-B, DNA damage, calcium channels, etc.

In normal conditions, mutated antigens from tumor cells will lead to the activation of T cells that bind to and trigger apoptosis in target cancer cells. On the surface of T cells are PD-1 (programmed cell death-1) receptors whose ligands include PD-L1 and PD-L2. Together, PD-1 and PD-L1/PD-L2 are involved with inhibiting T cell response so that the immune response is only initiated when necessary, avoiding chronic autoimmune inflammation. However, tumor cells have utilized the PD-1/PD-L1 pathway to resist anticancer immune responses by producing abnormally high levels of PD-L1. When the PD-L1 ligands bind to the PD-1 receptors on T cells, the T cells become deactivated and anti-tumor activity is obstructed.

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.

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!
