LAB BIOREAGENTS StrongBlock II Buffer 500ml
Lab Bioreagents StrongBlocks (I, II, III) are newly developed blocking buffers that provides exceptional performance and broad compatibility for Western blot, ELISA, IHC and nucleic acid detection assays The blocking buffer is to block excess binding sites on the micro-plate for reducing non-specific binding signal, by which the assay sensitivity and specificity are improved. As many factors can influence nonspecific binding, there is no single blocking buffer that is ideal for each assay. For example, depending on the recognition of detection probes from different assays, one individual blocking buffer may cross-react with detection probe. StrongBlocks (I, II, III) are a variety of buffers designed by different blocker components. During the assay, the test different blocking buffers helps to develop a immunoassay with low background noise and high signal-to-noise.
Cole-Parmer Oakton Traceable pH Standard Buffer with Calibration, Yellow, pH 7; 500 mL
Oakton pH buffers are compared against, and are traceable to, NIST Standard Reference Materials. Each bottle includes a NIST-traceable calibration report stating accuracy at 25C to 0.010 pH. Store at room temperature. NIST-traceable reference materials include a calibration report from an ISO 17034 and ISO 17025 accredited laboratory.
Biotium Propidium Iodide Buffer
Propidium iodide (PI) is a cell impermeable nucleic acid intercalating dye. Because PI is excluded from viable cells, it can be used to distinguish necrotic or late apoptotic cells with damaged plasma membranes from viable cells or early apoptotic cells with intact cell membranes. After entering cells and binding to DNA and RNA, the fluorescence of PI is enhanced 20- to 30-fold. PI can be used in flow cytometry and fluorescence microscopy. PI is also utilized as a counterstain in multicolor fluorescent imaging, but nuclear-specific staining requires digestion of cellular RNA. Properties: Orange/red solution; Store at 4°C, protect from light; Ex/Em = 535/617 nm (with DNA); C27H34I2N4; MW: 668.4; [25535-16-4].
