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.

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

Molecular Dimensions 50% PEG SMEAR BROAD 250ML
PEG is an effective crystallization agent due to its protein-protein interaction promoting properties. The BCS Screen overcomes the impracticality of sampling all PEG varieties that has led to a few variants predominating in the most common screens. PEG Smears are designed primarily for efficient screening of chemical space. It is generally thought that well-defined, single PEG species produce the best diffracting crystals. Thus, optimization might involve identifying the single PEG compound that produces the best crystal for structural studies. MOLECULAR DIMENSIONS INC mfg# MD2-250-261
