Several pre-formulated buffers are available for Alpha assays. These have have been developed to meet the varying needs of different Alpha assays, and one of them may be a good choice for an assay that you are developing. AlphaLISA Immunoassay Buffer (IAB) is a broadly-applicable buffer, used in most AlphaLISA immunoassays. This buffer ontains detergent and low salt, so it can be used to lyse cells in some assays. It is generally sufficient to expose the protein epitopes of membrane proteins for Alpha assay detection.

Mouse pharmacological models continue to play a large role in the study of human disease, and mouse tool reagents have shown high utility in immunology and cancer research for decades. It can often be quicker to learn about immunology and the regulation of immune responses using a syngeneic mouse model. However, working in mouse systems can often require the development of separate mouse reagents, if the therapeutic agent of interest does not cross-react with mouse. Find out how the AlphaLISA® human PD-1/PD-L1 and AlphaLISA mouse PD-1/PD-L1 binding assays provide a fast, powerful, homogeneous platform for obtain binding potencies from potential novel drug candidates.
Too many candidates, too little time. The lack of robust, rapid, high-throughput assays to identify and qualify potential therapeutic targets in areas such as cancer research continues to cost valuable time. What if you could increase assay throughput without compromising sensitivity, obtain more data points from each sample and eliminate tedious wash steps? Find out how AlphaLISA® assay technology, combined with the EnVision® multimode plate reader, provides a fast, powerful, homogeneous platform for screening potential inhibitors of PD-L1 (a protein associated with breast cancer tumor cells) expression in human cells.
Many tumor cells, which under normal, healthy conditions would be recognized by the body’s T cells and thereby targeted for destruction, have developed ways to evade the host immune system by taking advantage of immune checkpoint pathways. Among the most promising approaches to activating therapeutic antitumor immunity is through the blockade of immune checkpoints. The programmed cell death-1 (PD-1) immune checkpoint pathway is a negative regulator of T-cell immune function. When PD-1 is bound to programmed cell death-ligand 1 (PD-L1), T cell response is suppressed. Inhibitors that block PD-1/PD-L1 complex formation lead to increased activation of T-cells and immune system functions, allowing the body’s immune system to identify and attack tumor cells. So far, several anti-PD-1 or PD-L1 monoclonal antibodies have been developed to treat a variety of cancers, including non-small cell lung carcinoma (NSCLC), metastatic melanoma and renal cancer. The promise of therapeutically exploiting this pathway has created a need for more robust, straight-forward assays to identify and qualify potential inhibitors which interrupt PD-1/PD-L1 binding. Find out how AlphaLISA® technology provides a simple, homogenous, straightforward method for detecting PD-1/PD-L1 binding.
Biomarker levels were measured directly in CulturPlates-96 and-384 in a simple, fast, all-in-one-well AlphaLISA assay format. The elimination of transfer and wash steps simplifies cellular assays, reduces variability and significantly reduces hands-on time and costs associated with consumables. Integral plasma membrane (EGFR) and secreted solubleproteins (TNFa, IL1ß, IL6, IL8) were successfully determined, on adherent or suspension cells, using the standard AlphaLISA Immunoassay buffer.
The AlphaLISA® assay is a homogeneous immunoassay alternative to classical ELISA. AlphaLISA assays were originally utilized to detect analytesin cell cultures upernatants or serum/plasma samples.
Enzyme-linked Immunosorbent Assay is the most widely Kits adopted method for detection and quantification of cytokines and other biomarkers. This traditional technology offers good,selectivity, sensitivity and assay versatility; however, it has certain disadvantages such as limited dynamic range and low throughput due to the numerous wash steps.
