Having performance issues with your PCR Assay?

It is easy to mistake that one size fits all when choosing a PCR master mix for your amplification assay, leaving you on the edge of performance. Invest in quality and consistent results by optimizing your PCR master mix specific to your needs with the PCR Optimization Kit.

			Study reveals how dangerous bacterium shares its genetic information Bacteria are very sneaky in their efforts to develop resistance to antibiotics. Some strains of bacteria package up the genetic instructions for how they defend themselves and cause disease, and pass this information on to neighbouring, naïve, bacteria - essentially gifting their colleagues with the defences they need to survive against our medical armoury of antibiotics.

			Promising gene therapy for 'day blind' sheep now safe for clinical trials in human patients Back in 2009, a group of Israeli researchers identified a herd of Awassi sheep suffering from "day blindness". As its name implies, these sheep were blind during the day (in bright light) but could see at night, in low-light conditions.

	UTA scientist to provide new insights on the role of 'jumping genes' A biology researcher at The University of Texas at Arlington will be using the high-tech tools provided by the North Texas Genome Center to shed light on the role of 'jumping genes'.

	Brigham Genomic Medicine program unravels 30 medical mysteries A table in a recently published paper tells the story of 30 families who have, sometimes after years of searching, finally received an answer about the condition that has plagued one or more family members.

	Chromatin Remodeling: Mechanisms and Importance Chromatin remodeling is an important mechanism of regulating eukaryotic gene expression, which makes tightly condensed DNA accessible to various regulatory factors, such as transcription factors and components of DNA replication.

	KKH develops new test to enable faster diagnosis of critically ill children with rare diseases A multi-disciplinary team at KK Women's and Children's Hospital has developed a test to enable faster diagnosis of rare diseases to help critically ill children.

	Discovery of key mechanism may lead to more functional skin grafts for burn victims University of Colorado Boulder researchers have discovered a key mechanism by which skin begins to develop in embryos, shedding light on the genetic roots of birth defects like cleft palate and paving the way for development of more functional skin grafts for burn victims.

	Is ‘precision medicine’ the answer to cancer? Not precisely. Facing incurable breast cancer at age 55, MaryAnne DiCanto put her faith in "precision medicine" — in which doctors try to match patients with drugs that target the genetic mutations in their tumors. She underwent repeated biopsies to identify therapies that might help.

	Researchers use CRISPR to identify gene that helps cells resist flavivirus infection UT Southwestern researchers today report the first use of CRISPR genome-wide screening to identify a gene that helps cells resist flavivirus infection. That nasty class of pathogens includes West Nile virus, dengue fever, Zika virus, and yellow fever.

	Paracetamol use in infancy may increase risk of developing asthma by the age of 18 Children who take paracetamol during their first two years of life may be at a higher risk of developing asthma by the age of 18, especially if they have a particular genetic makeup, according to new research presented at the European Respiratory Society International Congress today.

	Study could pave way for new therapies to reverse aging in human cells Research has shed new light on genetic processes that may one day lead to the development of therapies that can slow, or even reverse, how our cells age.

	MicroRNA Profiling Methods and Applications MicroRNAs (miRNAs) are small, short non-coding RNAs that bind to specific messenger RNAs (mRNAs) and regulate gene expression either by degradation or by translational inhibition of the mRNA.

	Shotgun Metagenomic Sequencing Diverse microbial communities exist all around Earth, both within our bodies and our external environment.

	What is Spinocerebellar Ataxia? Ataxia is a degenerative disease affecting the nervous system, presenting poor coordination and movement, difficulties with speech, walking, fine motor skills, swallowing, and vision. It mainly affects people over 18 (adult-onset).

	What is Methylation-Specific PCR? DNA methylation is an important epigenetic process which has diverse roles to regulate gene expression, imprinted genes, inactivation of X chromosomes, and the dysregulation of these patterns in diseases.

	Study provides complete picture of HPV virus-head and neck cancer connections Human papillomavirus is widely known to cause nearly all cases of cervical cancer. However, you might not know that HPV also causes 70 percent of oropharyngeal cancer, a subset of head and neck cancers that affect the mouth, tongue, and tonsils.

	Scientists get unprecedented view of brain development through high-resolution genomic map Researchers at St. Jude Children's Research Hospital have created a massive database of the changes in gene activity of individual cells in the cerebellum during embryonic development and immediately after birth.

	The Microinjection System to Suit Any Application Single-cell microinjection system represents an innovative way to integrate exogenous material into cells and to extract and transmit cellular components between cells.

	Twice-a-year MRI more effective than mammograms for women with genetic breast cancer risk Getting magnetic resonance imaging scans twice a year instead of one annual mammogram is far more effective at detecting early breast cancers in young women with a high-risk genetic profile than mammograms alone, according to a research team based at the University of Chicago Medicine and the University of Washington, Seattle.
