These kits provide high-throughput screening platforms that help researchers quickly identify small molecule compounds or biologics that affect signaling.
    Study of disease mechanism. Abnormal signal transduction is closely related to the occurrence and development of many diseases, and signal transduction kits can be used to study the molecular mechanisms of these diseases. By analyzing changes in disease-related signaling pathways, researchers can better understand the pathogenesis of the disease and provide a basis for the development of treatment strategies.
    Cell function research. Signal transduction is the key to cell function regulation, and signal transduction kits can be used to study cell proliferation, differentiation, migration and other biological functions.
    Experimental techniques related to signal transduction. Flow cytometry, gel migration or electrophoretic mobility detection (EMSA), ELISA and other techniques are often used in signal transduction studies. Signal transduction kits are often combined with these experimental techniques to provide the necessary reagents and protocols to support accurate experimental operations and data analysis.

    Case Study

    Case Study 1: Notch1/CSL Reporter Kit (Notch Signaling Pathway) (Kit-1786)

    The family of Notch proteins plays a key role in cell fate determination. Additionally, Notch proteins regulate critical functions of the endothelium, as well as other recruited supporting cells, in concert with other pathways. Despite significant advances in the field and extensive studies focused on elucidating this pathway, many questions remain regarding Notch activation and its upstream/downstream effects, with vascular biology constituting one area of particular interest. Here, the researchers provide a brief description of the components and functions of the Notch pathway in vasculature, followed by a detailed compilation of recommended methods of evaluation in vitro and in vivo. They provide a rationale for key elements when choosing different approaches and controls, strengths and limitations, and essential considerations when providing a meaningful interpretation of results. The aim is to describe a careful approach to assessing Notch function in endothelial cells, based on underlying principles, with the overall goal of obtaining physiologically relevant information that will enhance our understanding of this pathway and its role in vascular biology.

    Case Study 2: cAMP Activity Assay Kit

    5-demethylnobiletin exhibits a broad spectrum of biological activities such as anti-cancer, anti-inflammatory, cardiovascular protective and neuroprotective effects, however, its effect in melanogenesis remains uninvestigated. The current work aims to confirm the bioactivity and mechanism of 5-demethylnobiletin in stimulating melanogenesis. Multiple biological assays on melanogenesis-associated proteins such as melanin content detection, tyrosinase activity colorimetric assay, cAMP activity assay and Fontana-Masson ammoniacal silver staining were used to confirm the role of 5-demethylnobiletin in stimulating melanin synthesis and the transportation of melanosomes. As confirmed by multiple biological assays, 5-demethylnobiletin is found to stimulate dendrite structure formation in cells, melanin synthesis and the transportation of melanosomes, via inducing the phosphorylation of cAMP response element-binding protein (CREB) and increasing the intracellular levels of cAMP in vitro through the PKA-dependent pathway.

    Fig2. B16F10 cells were incubated with 5-demethylnobiletin (2.5, 5 and 7.5 μM) for 30 min, and the changes of intracellular cAMP level were analyzed by using a cyclic AMP competitive Kit.

    Case Study 3: Cell Transformation Assay Kit

    This study focused on understanding matrix adhesion pathways that control the oral carcinoma response to cisplatin. The studies revealed that adhesion of HN12 and JHU012 oral carcinomas to carcinoma matrix supported tumor cell proliferation in response to treatment with cisplatin. Disruption of talin expression in HN12 cells adherent to carcinoma matrix increased cisplatin induced proliferation. Pharmacological inhibitors were used to determine signaling events required for talin deficiency to regulate cisplatin induced proliferation. Pharmacological inhibition of NF-kB reduced proliferation of talin-deficient HN12 cells treated with 30 µM cisplatin. Nuclear NF-kB activity was assayed in HN12 cells using a luciferase reporter of NF-kB transcriptional activity. Nuclear NF-kB activity was similar in HN12 cells adherent to carcinoma matrix and collagen I when treated with vehicle DMSO. Following treatment with 30 µM cisplatin, NF-kB activity is maintained in cells adherent to carcinoma matrix whereas NF-kB activity is reduced in collagen I adherent cells. Talin overexpression was sufficient to trigger NF-kB activity following treatment with cisplatin in carcinoma matrix adherent HN12 cells in a process disrupted by FAK siRNA.

    Fig3. HN12 cells transfected with talin cDNA expression vector together with tk-luciferase (lacking the NF-kB regulatory element) and renilla luciferase adherent to carcinoma matrix were treated with DMSO and 30 µM cisplatin.
