Protein Modification Reagents
Broadpharm TCO-PEG4-NHS ester, 1613439-69-2, MFCD28118912, 25mg
Formula: C24H38N2O10, Purity: 95%, MW: 514.6, TCO-PEG4-NHS Ester is a PEG derivative containing a TCO moiety and a NHS ester. The hydrophilic PEG spacer increases water-solubility and a decreases steric hindrance during ligation. This reagent can be used to label antibodies, proteins and other primary amine-containing macromolecules with TCO moiety.
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.

ATHENA ES REFOLDING KIT FOR PROTEINS
The QuickFoldTM Protein Refolding Kit is a screening kit that enables researchers to pinpoint the critical factors for refolding their protein in as little as 1 hour. Unlike many traditional kits, the Quick-FoldTM Kit employs a fractional factorial matrix design that allows the researcher to screen a specific protein in 15 different buffers quickly and easily. Researchers are able to examine a wider range of conditions all in a single experiment, simplifying the process of identifying the best buffer composition and method for the refolding of a given protein. The QuickFoldTM Kit comes with enough buffer for 10 refolding experiments, as well as supplemental Dithiothreitol and a Glutathione Redox System. Each buffer is available for individual purchase and is supplemented with the necessary Glutathione Redox System and/or DTT. Individual Buffers come in 500mL and 1L amounts.
TRIBIOSCIENCE INC DTT Solution (1M), DNase / RNase Free, 50 ML
Tribioscience’s Dithiothreitol (DTT) is used in proteomics applications to maintain sulfhydryl (-SH) groups in the reduced state and for quantitative reduction of disulfide (-S-S-) groups. By reducing the disulfide bonds in a protein sample, the protein can be more effectively fragmented and analyzed. The concentration is 1M.
Sigma Aldrich Fine Chemicals Biosciences Collagenase D
From Clostridium histolyticum. Collagenase D is prepared from Clostridium histolyticum cultures by filtration, ammonium sulfate precipitation, dialysis, and lyophilization. Collagenase D is recommended when functionality and integrity of cell-surface proteins are important.
