Quick Blocking for Perfect Westerns

When the milk gets old, it's time to throw it away. Our 5M QuickBlock Kit can completely block any solid surface in just five minutes, reaching the same level of antigen detection with smaller amounts of antibody. · Quick procedure: Efficiently blocks a western blot or ELISA plate in only five minutes. · Increased sensitivity: Significantly increases the ratio of signal over background noise, thus requires much less amount of antibody. · Wide range: Works with over 80% of the antibodies from the most popular species · Easy optimization: Determines the best blocking reagents for problematic antibodies · Low cost: The kits are designed only for blocking. There are no bundled reagents to inflate the price and depress your budget. Our customer representatives are available 24 hours, Monday through Friday. You may contact us anytime for assistance. Please check our contact page for our ocal reginal numbers.Western Blot Specialist Gen Script Corporation – VWR Strategic Partner 120 Centennial Ave., Piscataway, NJ 08854 Tel: 1-732-885-9188 ext 128 Fax: 1-732-210-0262

Purification of miRNA from FFPE Sections

Purification of miRNA from FFPE Sections

The miRNeasy FFPE Kit from QIAGEN enables purification of total RNA that includes miRNA and other small RNA from formalin-fixed, paraffin-embedded (FFPE) tissue sections including laser capture microscopy samples. Fixing tissues with formalin leads to RNA–RNA and RNA–protein crosslinking, which impairs RNA performance in downstream applications. The miRNeasy FFPE Kit reverses formalin crosslinking and releases RNA from tissue sections while avoiding further RNA degradation. Optimized binding conditions allow purification of all usable RNA from approximately 18 nucleotides upwards. The purified RNA delivers maximal performance in a range of applications, including real-time PCR. To find out more about the miRNeasy FFPE Kit and QIAGEN's comprehensive range of miRNA research technologies, please visit the link below.

Nanoparticle siRNA Transfection System

N-TER™ Nanoparticle siRNA Transfection System: siRNA Delivery to Difficult-to-Transfect Cells

Traditional lipid-based siRNA transfection reagents have a number of drawbacks, including a limited ability to transfect into a variety of cell types, such as primary, neuronal, differentiated, and non-dividing cells. Sigma's N-TER™ Nanoparticle siRNA Transfection System is a peptide based transfection reagent specifically designed to bypass these limitations and allow for efficient delivery of siRNAs into historically unapproachable eukaryotic cell lines.

Novel Luciferase Assay System for HTS Applications

Targeting Systems Offers a Novel Luciferase Assay System for HTS Applications
This product is based on gaussia luciferase, a secreted luciferase that is more than a 1000 times brighter than firefly or renilla luciferases. When it comes to screening compounds that affect the activity of a weak promoter, an assay type and readout method can make the difference between actually finding compounds or proteins of interest and not finding them. Gaussia luciferase is extremely attractive for drug screening involving weak promoters. Ease of use, elimination of cell lysis, signal stability, and high signal intensity make the Secreted Gaussia Luciferase System a powerful tool for high-throughput applications. Targeting Systems also offers a dual luciferase reporter system based on gaussia luciferase with firefly luciferase as the second reporter.

Reproducibility in Protein Biomarker Research WEBINAR

Reproducibility in Protein Biomarker Research WEBINAR

Please join our panel of experts on 5 December 2007 for a live online
educational seminar, "Tackling Reproducibility Issues in Mass
Spectrometry-based Biomarker Discovery."

Submit your questions LIVE to the experts during the webinar!

Date: Wednesday, December 5, 2007
Time: 12:00 noon EST; 9:00 am PST; 5 pm GMT
Duration: 1 hour

Register now! For more information and complimentary registration visit:

Mass spectrometry is an extremely powerful and sensitive technology that
can detect very small changes in expression levels. Some of these
changes may stem from the biological differences related to a disease or
treatment of interest. Others, however, may reflect the heterogeneity of
patients across multiple sites, the inherent biological complexity and
diversity of different sample types, and even small differences in
sample collection, processing, handling, and analysis techniques used by
multiple operators across multiple locations. As a consequence, data may
be tainted by site-, study-, population-, or sample-specific anomalies
and, therefore, not be sufficiently robust for biomarker discovery.

Join our panel of experts in a live, audience-driven Q&A as they discuss
how to overcome these reproducibility issues to generate less biased and
more reliable results. Questions for the panel can be submitted live
through your viewing console.
