Impure extracts generally contain a wide range of proteins with diverse biological functions and chemistry that need to be separated. GoldBio's IDA cross-linked agarose resins consist of iminodiacetic acid groups ligated by stable ether linkages via a spacer arm. IDA is a tridentate chelating agent, covalently coupled to cross-linked agarose beads. These resins are loaded with a divalent metal ions (such as nickel, cobalt, zinc or copper) in either high density or low density affinities to meet your specific research requirements. Copper ions have high affinity (binding strength) but low specificity (selectivity); cobalt ions have low affinity but have high specificity; while nickel and zinc combine a mid-ranged affinity and specificity for most general purposes.

analysis. At GoldBio, we offer different affinity resins and columns including aminoethyl and glyoxal agarose beads, Glutathione S-transferase (GST) and nitrilotriacetic acid (NTA) resins, antibody ̶ Protein A and Protein G ̶ and histidine-tagged protein purification resins, immobilized enzyme resins, and magnetic, crosslinked and plain agarose beads. Below, you will also find our tested and trusted buffers and washes as well as the necessary equipment to help you obtain optimal binding and elution and achieve a high protein yield in small batch or large scale assays. You can also access our extensive collection of resources, designed to simplify your protein isolation procedure, that consists of detailed protocols, video demos and troubleshooting guides.
Select Resin Products
- Our aminoethyl and glyoxal agarose resins, offered in low and high density formats, are designed for optimal protein immobilization since they have high binding capacity, high specificity, fast conjugation and provide highly reproducible results.
- We provide high-quality chromatography equipment including gravity columns, regular and spin-mini columns to use in fast protein liquid chromatography (FPLC) and medium pressure liquid chromatography (MPLC) as well as empty columns that can be customized for your specific protein purification assay.
- Our products also support affinity chromatography-facilitated isolation of recombinant proteins. GST-tagged proteins can be isolated through our glutathione resins in a one-step purification method allowing for rapid recovery. Histidine-tagged protein purification is made easy through our thoroughly tested cobalt, nickel, copper and zinc immobilized metal affinity chromatography (IMAC) IDA and NTA resins.
- We also offer nickel NTA magnetic agarose beads, which are a suitable and convenient alternative for small scale purification of his-tagged proteins in native or denaturing conditions. In addition, our ready-to-use washing and elution buffers, His-tag buffer set and imidazole are available to meet your purification needs.
- The high IgG-binding capacity, stability and specificity of our Protein A agarose resin and Protein G HTC agarose beads allows succesful isolation of classes, subclasses and fragments of immunoglobulins from crude samples.
- Our immobilized enzyme resins feature immobilized ficin, papain and pepsin agarose resins that facilitate the generation of F(ab’)2 fragments and small Fc peptide fragments. Immobilized pepstatin and trypsin agarose resins allow enrichment of a variety of specific macromolecules.
- We carry a large range of crosslinked and plain agarose beads for effective isolation of proteins through size exclusion chromatography.

Highest Density Nickel
Product Description
GoldBio’s new Highest Density Nickel Agarose is a high capacity resin manufactured with a polychelator ligand. The product was developed to work in the presence of EDTA and DTT without any loss of performance. Its specificity and stability allows a one-step purification, eliminating the need for pretreatment of samples that cause nickel stripping.
Our Highest Density Nickel Agarose is supplied as a suspension in 50% aqueous suspension containing 20% ethanol. Purifications can be performed using 20mM EDTA and 20mM DTT and can work in both native as well as denaturing conditions.
