Protein Modification Reagents
New England Biolabs, Inc. TEV Protease – 1000 units
TEV Protease is a highly specific cysteine protease that recognizes the amino-acid sequence Glu-Asn-Leu-Tyr-Phe-Gln-(Gly/Ser) and cleaves between the Gln and Gly/Ser residues. It is often used for the removal of affinity purification tags such as maltose-binding protein (MBP) or poly-histidine from fusion proteins. TEV Protease has a 7xHis-tag for easy removal from a reaction using nickel affinity resins and has been engineered to improve thermal stability and decrease autolysis.

Lyophilized FabALACTICA (IgdE) for digestion of 2 mg of human IgG1. FabALACTICA (IgdE) is a unique protease that cleaves human IgG1 at one single amino acid position just above the hinge region, generating intact Fc and Fab fragments
Worthington Biochemical Corporation COLLAGENASE TYPE 4 5X50MGCOLL
Collagenase, Type 4 (Code: CLS-4), which is filtered through a 0.22 micron membrane and lyophilized in vials.
LAB ALLEY Lab Alley Polyethylene Glycol (PEG) 400 Food Grade (FCC) Halal
Polyethylene Glycol is synthesized by ring-opening polymerization of ethylene oxide. This synthesis process gives PEG a range of molecular weights and distributions from 300 grams per mole to 10000000 grams per mole. PEG 400 has a molecular weight of 400 and is a clear colorless viscous liquid. Polyethylene Glycol is colorless inert odorless and non-volatile. PEG is biocompatible (it will not damage tissues or cells) hydrophilic dissolves readily in water without changing the color odor or taste and is nontoxic. Due to the high purity of Polyethylene Glycol 400 it is certified by the United States Pharmacopeia (USP) grade and the Food Chemicals Codex (FCC) grade.
