STEMCELL Technologies Collagenase Type IV (1 mg/mL), Size: 100 mL
Human embryonic stem (ES) cells are routinely passaged as clumps, rather than single cells. To generate clumps appropriate for passaging, both enzymatic and mechanical (by dissection or scraping) methods can be used. Collagenase Type IV is an enzyme that is routinely used at 1 mg/mL for the generation of human ES cell and iPS cell clumps for passaging.

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.

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.

Broadpharm Palmitic acid-PEG4-NHS ester, 100mg
Palmitic acid-PEG4-NHS ester is a saturated long-chain fatty acid with a 16-carbon backbone and a PEG linker connected to a terminal NHS ester. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The hydrophilic PEG spacer increases solubility in aqueous media.
