Poloxamer 122 (L42)

(Synonyms: PEG-PPG-PEG, 1630 (Average))

Poloxamer 122 L42 (PEG-PPG-PEG, 1630 (Average)) is a synthetic nonionic triblock copolymer composed of polyoxyethylene-polyoxypropylene, with emulsifying and wetting properties. Poloxamer 122 L42 forms large spherical aggregates in aqueous solutions near its cloud point,. Poloxamer 122 L42 can form thermoreversible hydrogels, and is also used in research related to serving as a drug delivery carrier in the fields of food additives, cosmetics, pharmaceutical preparations and tissue engineering.

Biological Activity

Description

In Vitro

Poloxamer 122 L42 (25°C) exhibits anomalous hydrodynamic radius and intrinsic viscosity in aqueous solution, which may result from the formation of large spherical aggregates near its cloud point at 32°C or the presence of optical inhomogeneity artifacts^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
