The DPPIV-Glo™ Protease Assay is a homogeneous, luminescent assay that measures dipeptidyl peptidase IV (DPPIV) activity. DPPIV is a serine protease that cleaves N-terminal dipeptides from polypeptides with L-proline or L-alanine at the penultimate position. The DPPIV-Glo™ Assay provides a proluminescent DPPIV substrate, Gly-Pro-aminoluciferin, in a buffer system optimized for DPPIV and luciferase activities. The addition of a…

Universal, HTS Kinase Screening Assays Use higher ATP concentrations: Linear response up to 500μM ATP. Use any kinase and kinase-substrate combination, including peptide, protein, lipid, and sugar substrates. Perform the assay without substrate modifications. Obtain reliable results: Z´-factor values routinely >0.7. Reduce false hits: Luminescence is much less susceptible to interference from library compounds t…

The ONE-Glo™ Luciferase Assay System provides a highly sensitive, robust, homogeneous assay for detection of firefly luciferase reporter gene expression in mammalian cells. Ideally suited for high- and ultrahigh-throughput applications, the ONE-Glo™ Assay contains a new luciferase substrate, resulting in a reagent that is more stable, more tolerant to sample components, and has less odor than standard luciferase assay reagents…

The ApoTox-Glo™ Triplex Assay combines three assay chemistries to easily assess viability, cytotoxicity and apoptosis events in the same cell-based assay well. First, viability and cytotoxicity are determined by measuring two differential protease biomarkers simultaneously with the addition of a single nonlytic reagent containing two peptide substrates. The live-cell protease activity is restricted to intact viable cells and i…

The VACUU·SELECT controller simpifies your work and allows VARIO® select chemistry diaphragm pumps to deliver unparalleled precision. Select from a set of predefined applications, modify an existing process or create your own using the drag-and-drop editor. The pumps run whisper-quiet and…

BRAND encoded PD-Tip™ syringe tips are manufactured from high-quality virgin plastics for use with most standard repeating pipettes in a wide variety of applications. PD-Tip™ syringe tips are made without lubricants or chemical additives to prevent reagent contamination. PD-Tip™ syringe tips can be used with the BRAND HandyStep® S and HandyStep® electronic repeating pipettes, the Eppendorf® Repeater® and EDOS® 5221; the Rai…

NEW! BRAND Ultra Low Retention tips feature a patented surface treatment to make the polypropylene of the pipette tips extremely liquid repellent thus reducing costly sample loss during pipetting. Ultra-hydrophobic tips are ideal for biological samples that contain detergents such as Triton® X-100, SDS, Tween etc. Special patented process does not use coatings that might lead to sample contamination Highly homogeneou…

The ECL Western Blotting Substrate is a highly sensitive non-radioactive, enhanced luminol-based chemiluminescent substrate for the detection of horseradish peroxidase (HRP) on immunoblots. The ECL Western Blotting Substrate detects picogram amounts of antigen, and with the use of photographic or other imaging methods, visualizes the presence of HRP. The ECL Western Blotting Substrate is a highly sensitive non-radioactive,…

PCR Master Mix(a,b) includes Nuclease-Free Water and PCR Master Mix, 2X. PCR Master Mix is a premixed, ready-to-use solution containing Taq DNA Polymerase, dNTPs, MgCl2 and reaction buffers at optimal concentrations for efficient amplification of DNA templates by PCR. The PCR Master Mix has been optimized for use in routine PCR for amplifying DNA templates in the range of 0.2–2kb.

The Griess Reagent System measures nitrite (NO2–), which is one of two primary stable and nonvolatile breakdown products of nitric oxide (NO). Nitric oxide is an important physiological messenger and effector molecule in many biological systems, including immunological, neuronal and cardiovascular tissues. This assay relies on a diazotization reaction that was originally described by Griess in 1879. Through the years, many mod…
