Beads & Microspheres

High capacity thiol reactive S3 Beads are one of Nanocs reactive agarose beads that can be used for reversible immobilization of biomolecules containing free thiol groups. S3TM thiol capture beads contain sulhydryl reactive bonds that can react easily with free thiol groups under mild conditions. Reaction between thiol and S3 resins results a reversible dithio bond that can be cleaved by common dithio reducing agents such as DTT or TCEP. Compared to other thiol reactive beads, Nanocs S3TM Beads have exceptionally high thiol capture capacity; Density of thiol reactive groups on S3 beads is 20-30 times more over conventional thiol activated agarose beads. S3 beads can be used in many applications, such as acyl-RAC protein assays; Protein S-palmitolyation pull down assay; Site-specific protein immobilizations; Protein purification, digestion and analysis. S3 beads are ideal replacements for commonly used activated Thiol-Sepharose 4B or Thiopropyl Sepharose 6B from GE.

Thiol functional agarose beads from Nanocs are intended to reduce disulfide bonds in biomolecules easily and efficiently. Unlike common disulfide bond reducing reagents, such as DTT, TCEP, our thiol functional agarose beads have free thiol groups covalently linked to the agarose surface and they can reduce disulfide bonds on the bead surface without any separation issue. These activated beads have free sulfhydryl groups that can also be used to attached various bio-ligands covalently to the bead surface. Covalently linked ligands offer high stability and are suitable for various biomolecule purification, capturing and assay. Nanocs surface modified agarose beads provide more choices than any other companies in this field. Customer conjugation and modification is available upon request.

Activated agarose (Pegarose) beads from Nanocs have uniform size in the range of 50~150 microns. These activated beads have multiple functional groups that can be used to attached various bio-ligands covalently to the bead surface. Covalently linked ligands offer high stability and are suitable for various biomolecule purification, capturing and assay. Nanocs surface modified agarose beads provide more choices than any other companies in this field.

NanoBright® gold nanoparticles from Nanocs have narrow size distribution yet with multiple size selection from 2 nm to 250 nm. These gold nanoparticles have spherical shape, completely soluble in water, have been used widely for the development of diagnostic probes, therapeutic agents and drug delivery vehicles. The optical and electronic properties of gold nanoparticles are tunable by changing the size, shape, surface chemistry and aggregate state. These gold nanoparticles can be further modified with different surface coatings and functional groups to render them with unique chemical and biological reactivity. Nanocs surface modified gold particles provide more choices for in-vitro or in-vivo applications of those nanoparticles.
