The BIOKÉ webshop is under construction until January 2nd, 2018. We wish you a successful 2018!
Using xCELLigence Real-Time Cell Analysis (RTCA), Sanofi Pasteur scientists have developed an assay for accurate viral titer determination that is 5-times less labor intensive and 3.5-times cheaper than conventional methods.
The measurement of contractility of Bronchial smooth muscle cells (BSMCs) and airway fibroblasts are important to study the pathogenesis of allergy/asthma and the mechanism of action of anti-allergic/asthmatic drugs. The conventional gel contraction assay is frequently used to study both fibroblasts and smooth muscle cells in vitro, but it is extremely laborious and low throughput.
T-Cell Marker Antibodies: Advancing Cancer Immunotherapy Breakthroughs
The Qsonica Q800R2 Sonicator offers an alternative method for mechanical DNA fragmentation for Illumina TruSeq® Library Preparation Kits.
NEB has evaluated a number of restriction enzymes for simple genomic DNA fragmentation in droplet digital PCR assays. This list is not meant to be exhaustive, but provides a starting point for validated enzymes with some simple usage guidelines. Each restriction enzyme listed below was successfully used for a ddPCR digest directly in the Bio-Rad® Droplet Digital SuperMix.
Read this publication in Nature Communications about the successful RNA purification for downstream RNA sequencing with the NucleoSpin RNA Plus Kit.
The expansion of flow cytometry applications from cellular analysis to molecular and genomic analysis, and the increase in availability of monoclonal antibodies and fluorochromes have magnified the demand for flow cytometers with expanded fluorescence detection channels. ACEA NovoCyte flow cytometers are configured with 561nm laser to meet the needs of multicolor analysis, broadening application capabilities in both basic research and clinical studies.
Advances in immuno-oncology have successfully led to novel cancer therapeutics with favorable patient responses that are more durable than conventional cytotoxic chemotherapy (1). However, not all patients respond to immunotherapy; therefore investigators are trying to identify clinically relevant biomarkers with the goal of developing therapeutics based on personalized medicine (2,3).
Forward genetic screens are powerful tools for the unbiased discovery and functional characterization of specific genetic elements associated with a phenotype of interest. Recently, the RNA-guided endonuclease Cas9 from the microbial CRISPR (clustered regularly interspaced short palindromic repeats) immune system has been adapted for genome-scale screening by combining Cas9 with pooled guide RNA libraries. Here we describe a protocol for genome-scale knockout and transcriptional activation screening using the CRISPR-Cas9 system.
Read about the advantage of using NucleoBond Endotoxin Free Plasmid DNA from MACHEREY-NAGEL to avoid endotoxicity in virus production and mammalian cell culture.
Struggling with DNA isolation from hard-to-lyse samples? Up to 60% more DNA compared to standard extraction methods.
Probe sonication is highly effective for processing nanomaterials (carbon nanotubes, graphene, inks, metal oxides, etc.). Sonicators have become the industry standard for different applications.
Cell lysis, tissue disruption and homogenization are common Sonicator applications. The ultrasonic energy output of each Sonicator model is adjustable and sonication parameters can be optimized according to your process requirements.
This application note describes how to assembly multiple fragments and have 100% correct clones.
An accurate and cost-effective total workflow solution for the characterization of EGFR in FFPE material.
This application note presents data showing the performance of the RainDrop Digital PCR system on FFPE DNA and low input cell free DNA (cfDNA) using the ThunderBolts Cancer Panel.
The RainDrop system lower limit of detection for the KRAS p.G12D (c.35 G>A) mutation is 1/45,000 (3.5E+07 WT copies examined). This highly sensitive and specific method has the potential to be employed in the clinic, including diagnosis, cancer recurrence monitoring, and treatment management.
After nearly 40 years of offering restriction enzymes to the research community, New England Biolabs (NEB) has earned the reputation of being a leader in enzyme technologies. NEB offers scientists 276 restriction enzymes, the largest selection in the industry.
A PhD student working at the Department of Immunology at the University Medical Center Utrecht shares her positive experience with the NucleoBond Xtra Midi Kit from MACHEREY-NAGEL
Visualization of Wnt receptor internalization by SNAP-tag technology from New England Biolabs (NEB)
The epigenetic status of genes can be assayed by chromatin immunoprecipitation (ChIP). ChIP is a powerful technique to study DNA-protein interactions. To explore the genome-wide binding of transcription factors and the epigenetic landscape ChIP can be combined with sequencing (ChIPseq). This technique enables exploration of the epigenetic state in a global fashion
In this application note we describe the use of the Gibson Assembly™ Master Mix from New England BioLabs (NEB) together with gBlocks™ Gene Fragments from Integrated DNA Technologies (1) for the creation of a basic cloning vector for IP3R research.
Validating an antibody for immunohistochemistry (IHC) use involves more than just observing a signal in cells.
