Unravelling the Metastatic Mechanism of Melanoma
Research has uncovered the mechanism of melanoma spreading; the findings could lead to a cure for the disease.
Gene Therapy Via Ultrasound
Research into a gene therapy approach called sonoporation could help combat heart disease and cancer.
Novel MRI Technique Distinguishes Healthy Prostate Tissue from Cancer
The UTSW researchers have determined that glucose stimulates release of the zinc ions from inside epithelial cells, which they could then track on MRIs.
Precision Nanobots Target Cancerous Tumours
Researchers achieve breakthrough toward redefining anti-cancer drug administration using nanorobotics.
PARP Proteins Explore Therapeutic Targets in Cancer
Researchers at UTSW have identified a previously unknown role of a certain class of proteins that opens the door to explore therapeutic targets in cancer and other disease.
Novel Therapeutic Approach for Blood Disorders
Gene editing of human blood-forming stem cells mimics a benign genetic condition that helps to overcome sickle cell disease and other blood disorders.
Immune-Cell Population Predicts Immunotherapy Response in Melanoma
All patients with high levels of one immune-cell type responded to treatment.
Effects of Chemotherapy on Developing Ovaries in Female Fetuses
Researchers at University of Edinburgh have shown that etoposide can damage the development of the ovaries while a fetus is in the womb.
Breast Tumors Evolve in Response to Hormone Therapy
Researchers have suggested that analyzing a single sample of the breast tumor is insufficient for understanding how a patient should best be treated.
Cutting off the Cancer Fuel Supply
Research from investigators at Rutgers Cancer Institute of New Jersey and Princeton University has identified a new approach to cancer therapy in cutting off a cancer cell’s ‘fuel supply’ by targeting a cellular survival mechanism known as autophagy. The co-corresponding authors of the work are Rutgers Cancer Institute Deputy Director Eileen P. White, PhD, and researcher ‘Jessie’ Yanxiang Guo, PhD.

Sequence-Specific DNA Assay

Molecular Devices

Measurement of specific DNA sequences can be achieved using the Threshold® System. Biotinylated and fluoresceinated oligonucleotide probes specific to the target sequence to be measured are used with the Immuno Ligand Assay (ILA) kit components. The probes are chosen so that they both anneal to the same strand of the target, adjacent to each other. DNA samples to be measured are digested with an appropriate restriction enzyme to liberate the target sequence on a small DNA fragment. The digested DNA is denatured in the presence of an excess of the biotinylated and fluoresceinated probes. The probes and denatured target are allowed to anneal, generating probe-target hybrids. These probe-target hybrids are captured on the biotinylated Threshold sticks using the ILA capture reagent (streptavidin) which binds to the biotinylated probe. The captured probe-target hybrids are then detected and quantitated using the ILA enzyme reagent (antifluorescein- urease conjugate) which binds to the fluoresceinated probe. This application note is intended as a guide and does not represent a validation of this assay, nor necessarily the optimal performance parameters for all probe and target DNA combinations.
