We are happy to announce the release of our new Boron Assay Kit! (DBOR-100)

BORON is an essential micronutrient in plants and is involved in maintaining robust cell walls, cell membranes, and reproductive tissues. Although boron is common in the soil in its natural state as a borate mineral, the amount of boron available to plants is actually quite small. As a result, boron deficiency is the second most common micronutrient deficiency among crop plants. In order to keep plant boron levels in a healthy range, supplementation to the soil via fertilizers and additives is often required. If not regulated, a lack of or excess of boron may significantly lower crop yield. In the biotech industry, sodium borohydride is commonly used to conjugate antibodies and typically needs to be removed from the final product, especially for therapeutic antibodies.

BioAssay Systems' boron detection kit provides a convenient and reliable means to measure boron. In the assay borate complexes with azomethine-H to create a colored compound that can be measured at 420 nm. This assay can be used with a variety of samples and is simple, sensitive, and adaptable to high-throughput screening.

We are happy to announce the release of our new Biotin Assay Kit! (DBIO-100)

BIOTIN , or Vitamin B7, is a water soluble vitamin involved in metabolism, cell growth, and protein synthesis. It is a cofactor to multiple carboxylases necessary for metabolizing fatty acids, glucose, and amino acids. Biotin is found in a wide range of foods and is often taken as a dietary supplement. In the biotechnology industry, biotin is commonly conjugated to proteins in a process called biotinylation. These biotinylated proteins can then be specifically selected using streptavidin and/or avidin's strong affinity for biotin in biochemical assays such as ELISAs.

BioAssay Systems' Biotin Assay Kit is based on avidin's weak affinity for 4'-hydroxyazobenzene-2-carboxylic acid (HABA) and strong affinity for biotin. The avidin-HABA complex reagent has an absorbance at 500nm. When the colored avidin-HABA reagent is introduced to biotin, the biotin binds to avidin, displacing the HABA and causing a decrease in absorbance. The decrease in absorbance at 500nm is directly proportional to the biotin in the sample.

We are happy to announce the release of our new Albumin Quick Test Strips!

ALBUMIN is the most abundant plasma protein in humans. Albumin plays many important physiological roles, including maintenance of colloid osmotic pressure and binding of key substances such as long-chain fatty acids, bile acids, bilirubin, haematin, calcium, and magnesium. Serum albumin is a reliable prognostic indicator for liver disease, nephritic syndrome, malnutrition, protein-losing enteropathies, as well as morbidity and mortality. In addition, elevated levels of serum albumin are associated with dehydration. Detection of albumin in urine is also crucial for diagnosis of patients with albuminuria disease.

BioAssay Systems' QuantiQuik™ Albumin Test Strips are based on the immobilization of an albumin sensitive chromagen onto a pad. Albumin will react with the chromagen and produce a colored product. The intensity of the product color is directly proportional to the albumin concentration in the sample. The QuantiQuik™ Albumin Test strips are a rapid and inexpensive method for semi-quantitative determination of albumin that does not require sophisticated laboratory instruments.
