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.
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.

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.
Worthington Biochemical Corporation COLLAGENASE 4KU CLSPA
Chromatographically purified. <50 caseinase units per milligram. Supplied as a lyophilized powder.
Formumax Scientific Inc DOXOVES- PEGYLATED LIPOSOMAL
Doxoves® - PEGylated Liposomal Doxorubicin HCl (2.0mL, 2.0mg/mL)Doxorubicin HCl is loaded into PEGylated liposomes composed of HSPC/CHOL/mPEG2000-DSPE (56.2:38.5:5.3 mol/mol) with ammonium gradient by the active loading approach. It is comparable to the commercial product DOXIL®. The liposomes are prepared to very high quality with consistent lot-lot characteristics. Narrow particle size distribution and high drug encapsulation efficiency. Note the high drug concentration (4mg/mL compared to 2 mg/mL for DOXIL®) allows the researchers to perform experiments at higher concentration/doses.Plain control liposomes for this product: F30204B-C2-2 (please inquire)Product For Research only and NOT for Human Use
