"CytoGroup 30nm NHS-activated Gold Nanoparticle Conjugation Kit have been optimized for high efficiency one-step covalent conjugation of proteins and other primary amine-containing ligands to gold nanoparticles.\nThe kit contains ready-to-use pre-made mixtures. No activation or manipulation of the gold nanoparticles is required prior to conjugation, which often results in poor performing conjugates. Simply mix your protein with the pre-activated NHS ester gold nanoparticles supplied in the kit. \nThis mini kit contains 10 individual reaction vials with lyophilized NHS-activated gold nanoparticles for performing ten independent conjugation reactions.\nKit Components\n\n30nm NHS-Activated Gold Nanoparticles (lyophilized) - 10 vials\nProtein Resuspension Buffer - 1.5ml\nReaction Buffer - 1.5ml\nQuencher Solution - 1.5ml\n\nFeatures &amp; Benefits\n\nResults in covalently bound ligand and more stable conjugate.\nFast and convenient one-step conjugation reaction with no pre-activation requirements.\nSpacer between the gold nanoparticle surface and conjugated ligand minimizes effects on the tertiary protein structure, which can lead to poor performing conjugates, a common problem seen in conjugates prepared by passive adsorption.\nPrecisely engineering surface coating that reduces non-specific protein binding in biological assays.\n\nGold Nanoparticle Specifications\nSurface functionality: NHS-ester (~ 1 NHS group/nm2) (5kDa PEG-spacer between gold surface and NHS-group)\nCore diameter: 30nm \nConcentration: OD=20 (when dissolved to a final volume of 100ul)\nParticles per ml: ~3.58E+12 (when dissolved to a final volume of 100ul)\nAbsorbance (lambda max): 526nm\nProduct Data\n\n\n\n\nDiameter \nPeak SPR Wavelength (nm)\nNPS/ml*\nWt.
