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

Alkali Scientific PEG 8000 [Polyethylene Glycol 8000], 1 Kg

Polyethylene Glycol 8000 (PEG 8000) is a high-molecular-weight polymer commonly used in molecular biology and biochemistry for molecular crowding experiments. It serves as a non-toxic agent that mimics crowded environments within cells to study macromolecular interactions. PEG 8000 is used to precipitate proteins, promote enzyme stability, and assist in DNA extraction protocols. This reagent is particularly useful in biochemical assays and can be employed in a wide range of molecular biology applications, such as protein crystallization, enzyme reactions, and gene expression studies. This product is available in a convenient 1 kg bottle for laboratory use.
