Sigma′s FLAG Immunoprecipitation kit allows a rapid and efficient immunoprecipitation and elution of an active FLAG-tagged protein. 

For use to enrich for specific regions of chromatin that are immunoprecipitated with a specific antibody for a chromatin protein. Works with all eukaryotic cell types. Detection of the gene or promoter of interest in immunoprecipitated chromatin must be empirically determined by the researcher. Quantitative PCR detection is recommended.

R&D Mouse IL-1 beta/IL-1F2 Quantikine ELISA Kit - R&D Mouse IL-1/IL-1F2 Immunoassay for the quantitative determination of mouse interleukin 1 beta (IL-1ß) concentrations in cell culture supernates and mouse serum. The R&D Quantikine Mouse IL-1 Immunoassay is a 4.5 hour solid phase ELISA. This R&D Quantikine assay employs the quantitative sandwich enzyme immunoassay technique. Features of the R&D Quantikine ELISA Kit inclu…

Each VECTASTAIN® ABC kit utilizes the same preformed Avidin: Biotinylated enzyme Complex (ABC) principle and all offer low backgrounds and an amplification of signal compared to conven-tional covalent conjugates. The high sensitivity reported for this technique likely resides in either the form or the number of active enzyme molecules associated with the complex and the rapid, irreversible interaction of the complex with bio…

Single molecule array (Simoa) testing is a protein detection technique that is orders of magnitude more sensitive than standard sandwich based immunoassay techniques. Traditional ELISA measurements are limited to pg/ml levels of detection. The RayBio Ultrasensitive Simoa Testing Services can achieve sensitivity as low as femtogram (fg/ml) levels, allowing the quantification of biomarkers at concentrations previously difficult…

The RayBiotech Monkeypox Virus 1-Step High Throughput PCR Kit is a ready to use PCR assay for the detection of monkeypox virus (MPXV) DNA. The 1-Step Nucleic Acid Stabilization Buffer eliminates the need for DNA extraction and purification steps.

COMET™ is a fully automated, high-throughput, hyperplex platform for the analysis of Formalin-Fixed, Paraffin-Embedded (FFPE), and frozen tissues.

Tools to acelerate biomarker identification and validation

Complement biomarker assays target selected biomarkers of high relevance. These assays are important and well-suited for analyses in drug development and academic research. They stand out with very low cross-reactivity and high specificity as they bind neo-epitopes of cleaved products or complexes, where this is relevant.

Purified antibodies are indispensable in spatial biology, providing unparalleled detail in cellular and molecular structure characterization. Our high-quality purified antibodies offer exceptional specificity, sensitivity, and reproducibility for diverse applications, from basic research to clinical diagnostics. Moreover, our purified carrier-free antibodies are ready to conjugate (RTC), streamlining your workflow.

Aura® is the particle and aggregate detection system that combines Backgrounded Membrane Imaging which images 100% of your sample to give you count, size, and morphological information, with up to 2 channels of Fluorescence Membrane Microscopy. Identify if particles are protein or not with the first FMM channel and determine if your sample contains lipids, hydrophobic entities, or other aggregates of your choice with a second…

Aura® PTx gets you to your best formulation faster! Backgrounded Imaging (BMI) technology to give you accurate count, size, and morphology information about particles in your sample. Couple that with Fluorescence Membrane Microscopy (FMM), which gives you definitive ID of protein aggregates and an easy way to monitor polysorbate degradation.

For quantitative detection of rat EGF in cell culture supernates, serum, plasma(heparin, EDTA), tissue homogenates and urine.
