Human Sweet and Umami Taste Receptor Variants

The complexity of taste discrimination (salty, sour, sweet, umami and bitter) varies between human individuals and populations. Sweet and umami (the taste of glutamate) tastes play a major role in the perception of calorically-rich and essential nutrients and there are well-documented differences in individual perception of sweet and umami flavorings, many of which appear to be genetic in origin.

Transformation-Associated Recombination (TAR) Cloning

Transformation-Associated Recombination (TAR) cloning in yeast is a unique method for selective isolation of large chromosomal fragments or entire genes from complex genomes without the time-consuming step of library construction.1 The technique involves homologous recombination during yeast spheroplast transformation between genomic DNA and a TAR vector that has short (approximately 60bp) 5’ and 3’ gene targeting sequences (hooks).

Monoclonal Antibody for Lyme Disease Diagnostic and Research

The hybridoma producing a monoclonal antibody against the major flagellin protein (FlaB) is available for licensing. This antibody can be used in diagnostic and research applications related to Lyme disease or other Borrelia-caused conditions. More information about this antibody can be found in Barbour et al., Infection and Immunity, May 1986, volume 52(5), pages 549-554.

Development of Gene Chip Technology for Vascular Risk Assessment

Prevention of cardiovascular disorders such as myocardial infarction and stroke is an area of major public health importance. Currently, several risk factors for future cardiovascular disorders have been described and are in wide clinical use in the detection of individuals at high risk. However a large number of cardiovascular disorders occur in individuals with apparently low to moderate risk profiles, thereby limiting the ability to identify such patients. Moreover, many of the risk factors require accurate gathering of clinical information.

Novel Methods for Using Biomarkers to Monitor Glucose Levels and Screen for Diabetes Risk

A primary goal of diabetes therapy is to improve control of blood glucose levels (known as glycemic control) in patients. Prospective studies of both Type 1 and Type 2 diabetes indicate that careful glycemic control significantly reduces the risk of microvascular, neurological, and cardiovascular complications of diabetes. The current method of monitoring glycemic control involves measuring levels of the intracellular hemoglobin (HbA1C).

Treatment and Prevention of Inflammatory Bowel Disease (IBD) using Mutant and Chimeric IL-13 Molecules

Ulcerative colitis (UC) is a chronic inflammatory disease of the colorectum and affects approximately 400,000 people in the United States. The cause of UC is not known, although an abnormal immunological response to bacterial antigens in the gut microflora is thought to be involved. Present treatments for UC include anti-inflammatory therapy using aminosalicylates or corticosteroids, as well as immunomodulators and diet.

A New Mouse Monoclonal Antibody Against Human Microphthalmia Transcription Factor (MITF)

Micropthalmia Transcription Factor (MITF) plays an important role in melanocyte development and melanoma growth. MITF is important for embryonic development, regulating the generation of pigment cells and formation of melanomas and other tumors. MITF is made in various isoforms that may play unique roles for different organs during different developmental periods. Additionally, tissue MITF levels can serve as a molecular marker for the diagnosis of metastatic melanoma and therapeutic response.
