Supplier: Invitrogen
Description: Thermo Scientific EZ-Link Sulfo-NHS-LC-LC-Biotin enables simple and efficient biotin labeling of antibodies, proteins, and any other primary amine–containing macromolecules. Specific labeling of cell surface proteins is another common application for these uniquely water-soluble and membrane impermeable reagents.
Catalog Number: (PI20700)
Supplier: Invitrogen
Description: Thermo Scientific Pierce DMS is dimethyl suberimidate, a membrane-permeable crosslinker that contains an amine-reactive imidoester group at each end of an 8-atom spacer arm.

Supplier: Invitrogen
Description: Thermo Scientific Pierce DSG is a water-insoluble, homo-bifunctional N-hydroxysuccinimide ester (NHS-ester) crosslinker often used for conjugating radiolabeled ligands to cell-surface receptors. The NHS ester is the simplest and most commonly used reactive group for crosslinking and labeling proteins and peptides. NHS esters react with primary amines on the N-termini of peptides and the  amine of lysine residues, forming a stable, covalent amide bond and releasing the NHS group.
Supplier: Invitrogen
Description: Pierce™ Recombinant Protein A agarose is a beaded agarose resin to which a genetically engineered form of Protein A has been immobilized for use in IgG purification applications where the native ligand has undesirable effects.
Supplier: Invitrogen
