Goldbio affordable reagents for electrophoresis, media culture, recombinant protein production & purification

During the 1980s, Dr. Paul Gold stepped out from behind the bench believing researchers needed a low-cost, high-quality alternative for chemicals and reagents. Recognizing his knack for business, he began brewing the idea for a company during a time when startup incubators were nearly unheard of, and the Internet, social media and crowdfunding didn’t exist. Armed with a supportive wife, generous family members and helpful people within his network, Dr. Gold established GoldBio in 1986. The original main office was situated in the former St. Louis Technology Center (now the location for the St. Louis Science Center), while the first lab space was located at St. Louis University. The ambitious startup began its journey selling three products: IPTG, X-Gal and X-Gluc. Now, after more than 30 years, GoldBio has evolved significantly, expanding its catalog from three products to more than 3000 products. Throughout its history, GoldBio’s success has relied on its commitment to the success of those whom we supply. At GoldBio, we believe that putting our quality products in capable hands leads to discoveries that impact the entire world.     GoldBio Product Directory: Affinity Reagents Affinity reagents and affinity-based tools utilize complex networks of specific interactions between various molecules for use in the separation, purification or analysis of proteins. Affinity purification requires an affinity ligand to be coupled to a matrix, which allows capture of the intended product from a complex mixture. Gold Biotechnology’s affinity reagents are activated beads or preactivated resins for use in coupling of affinity ligands and immobilization. Our affinity beads are specifically engineered to meet your specialized needs, whether it be laboratory scale experiments or industry scale separations. GoldBio’s agarose beads are conveniently cross-linked to include any of the following: aminoethyl or glyoxal groups, glutathione S-transferase, Protein A, Protein G, streptavidin and His-tag metal ions such as nickel, cobalt, copper or zinc.

  Reducing Agents Reducing Agents, sometimes referred to as reductants or reducers, are elements or compounds that lose an electron to some other chemical species in a redox chemical reaction. A reducing agent is usually in one of its lower oxidation states and is known as the electron donor. Reducing agents are typically used in protein solutions in order to cleave the disulfide bond between cysteine amino acids, but most are used in a variety of other applications across many fields of science. GoldBio has a number of reducing agents available, including DTT (dithiothreitol), glutathione, DTE (dithioerythritol) and TCEP. GoldBio Reducing Agents are Proven and Published™ ensuring quality agents with optimum potential.
