Blue Tetrazolium chloride is a chemical compound used for sensitive detection of alkaline phosphatase. With immunohistochemistry blue tetrazolium is used as a diagnostic for diseases of the phagocyte function by gauging the resulting blue color in the presence of oxygen formed by the phagocyte while killing bacteria.

The BLUEstain™ 2 Protein ladder is a three-color protein standard with 13 prestained proteins, covering a wide range molecular weights from 3.5 to 245 kDa. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-glycine buffer).

The BLUEstain™ 2 Protein ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. The ladder is supplied in gel loading buffer and is ready to use. Do not heat, dilute or add reducing agent before loading.

The BLUEstain™ Low Range Protein Ladder, 2 to 40 kDa is a ready-to-use three-color protein standard with 6 pre-stained proteins covering a range of molecular weights from 2 to 40 kDa. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 10 kDa and 40 kDa respectively) when separated on SDS-PAGE.

BLUEstain™ Low Range Protein Ladder is designed for monitoring protein separation during SDS-PAGE electrophoresis, verification of Western transfer efficiency on membranes (PVDF or nitrocellulose) and for approximating the molecular weight of small proteins. The ladder is supplied in gel loading buffer and is ready to use. Do not heat, dilute or add reducing agent before loading.

Bluo-Gal is used as an alternative to X-Gal, and produces a darker blue color. Bluo-Gal is hydrolyzed by β-galactosidase to produce a blue precipitate. This precipitate is insoluble in alcohol and xylenes, thus making it suitable for immunoblotting and immunocytochemical assays. Bacterial colonies containing active β-galactosidase produce blue colonies when grown on plates containing Bluo-Gal.

Bone Morphogenetic Proteins (BMPs) belong to the TGF-β (Transforming Growth Factor) superfamily of structurally related signaling proteins. BMP2 is a potent osteoinductive cytokine, capable of inducing bone and cartilage formation in association with osteoconductive carriers such as collagen and synthetic hydroxyapatite. In addition, BMP2 plays an important role in cardiac morphogenesis and is expressed in a variety of tissues; including the lung, spleen, brain, liver, prostate, ovary and small intestine. The functional form of BMP2 is a 26kDa protein composed of two identical 115 amino acid polypeptide chains linked by a single disulfide bond.

Sterile Filtered White lyophilized powder. Purified and tested for use in cell culture.

Bone Morphogenetic Proteins (BMPs) belong to the TGF-β (Transforming Growth Factor) superfamily of structurally related signaling proteins. BMP7 is one of at least 15 structurally and functionally related BMPs, originally identified as protein regulators of cartilage and bone formation which have since been shown to be involved in embryogenesis and morphogenesis of various tissues and organs. BMPs have been shown to regulate the growth, differentiation, chemotaxis and apoptosis of a variety of cell types; including mesenchymal cells, epithelial cells, hematopoietic cells and neuronal cells. The active form of BMP7 can consist of a dimer of two identical proteins or a heterodimer of two related BMPs. BMP7 is expressed highest in the kidneys and is genetically linked in mice to eye, skeletal and kidney development.

Bovine Gamma Globulin (BGG) is a versatile and high-purity product derived from the immune system of bovines. BGG is primarily used in the production of vaccines, serums, diagnostic reagents, and medical treatments. BGG serves as a passive blocker to reduce non-specific binding and mitigate heterophilic antibody interference in assays, making it a valuable tool in both research and diagnostic applications. Its effectiveness can be optimized by tailoring blocking conditions to maximize the signal-to-noise ratio and comparing results against appropriate controls.

Bovine Gamma Globulin is widely used in research to study protein-rich hyaluronan solutions affecting artificial articular joints, detect immunoglobulin G in bovine colostrum and milk using SPR-immunoassays, and investigate immunotolerance mechanisms. Its biochemical and physiological properties are closely aligned with those of human serum components, as demonstrated by advanced analytical techniques such as chromatography and electrophoresis.

GoldBio BGG is manufactured in a closed loop system to ensure consistent quality and reproducibility.

GoldBio’s Cohn Analog BSA is a highly purified, lyophilized “Fraction V” bovine serum albumin designed for sensitive applications in cell culture, microbial culture, reproductive biology, and molecular biology. Derived from the plasma of USDA-inspected healthy animals in U.S.-based facilities, this lyophilized “Fraction V” powder is produced using a proprietary, non-solvent procedure, including membrane dialysis, filtration, and a modified Cohn/heat-shock procedure, to inactivate proteases and minimize analytes.
