General description
Pluronicpluronic® F-127, also known as poloxamer 407, is a non-toxic[1] and nonionic copolymer. It contains polyethylene oxide-polypropylene oxide arranged in a triblock structure to form PEO-PPO-PEO symmetric. Surfactant properties of this polymer derived from its amphiphilic nature, allow them to interact with hydrophobic surfaces and biological membranes.
Application
Pluronic® F-127 has been used:
- as a delivery system for a peptide to the wound site to study the effect of the peptide on wound healing in mice.
- as a surface coating for PDMS (polydimethylsiloxane) stamps to make them hydrogel repellent.[2]
- in the preparation of calcium indicator stock solution for measuring neural activities.
- as a component of phosphate-buffered saline (PBS), to lower unspecific cell and protein adhesion to a PDMS-based microfluidic device.[3]
- This non-ionic copolymer surfactant is suitable for use in insect cell culture applications as an antifoaming agent.
Biochem/physiol Actions
Pluronic® F-127 is a thermo-reversible gel that finds its application in different industries due to its high thermosensitivity, biodegradability, and biocompatibility properties.[1] These properties make this polymer suitable for use as a versatile drug carrier.Pluronic® F-127 improves the therapeutic efficiency of drugs by increasing their bioavailability and thermostability. Additionally, it can promote cellular attachment and collagen formation, which facilitates angiogenesis and tissue regeneration. Due to its efficacy, Pluronic F-127 has been utilized in the encapsulation of mesenchymal stem cells (MSCs) to aid in the regeneration of tissues with low levels of vascularity, such as epithelial tissues, adipose tissues, cartilage, tendons, and bone tissues.[1]

What is the hydroxyl number of F127?
1 answer-
Based on an approximate molecular weight of 12,600, this block co-polymer with two hydroxyl groups has a theoretical hydroxyl value of 8.9 mg potassium hydroxide (KOH) per gram of polymer. Higher experimental results for the hydroxyl value would indicate some branching.

Is there a reference for using Pluronic F-127 to reduce cell adhesion in a microfluidic PDMS-based device? Also, does it dissolve in cell culture media in a PDMS-based device, and if it does, what modifications are recommended to maintain its ability to prevent cell adhesion?
1 answer-
There are several representative publications that report the use of Pluronic F-127 to lower cell adhesion on microfluidic PDMS-based devices. These publications may be of interest as a reference:
Curr Protoc Cell Biol. 2017 Jun 19;75:10.21.1-10.21.8. Microcontact Peeling: A Cell Micropatterning Technique for Circumventing Direct Adsorption of Proteins to Hydrophobic PDMS. PMID: 28627756
Sci Rep. 2019 May 14;9(1):7377. Simple Surface Modification of Poly(dimethylsiloxane) via Surface Segregating Smart Polymers for Biomicrofluidics. PMID: 31089162
Lab Chip. 2009 Jun 7;9(11):1500-3. Surface modification of PDMS by gradient-induced migration of embedded Pluronic. PMID: 19458853
These publications provide information on using Pluronic F-127 to lower cell adhesion on PDMS-based devices. As for its solubility in cell culture media within a PDMS-based device and the recommended modifications to maintain its ability to prevent cell adhesion, it is advised to refer to these publications for detailed insights.

I was asked about the polydispersity of Pluronic F-127, Product P2443. Could you please inform me?
1 answer-
The polydispersity is not a test specification for this product. The product is an ABA-type copolymer of poly (ethylene oxide) (PEO=A) and poly (propylene oxide) (PPO=B), where the A and B blocks have the following values: A = 101, B = 56. The approximate relative amount of PEO in the poloxamer is ca. 70% and the average molecular weight of the PPO is 4000. The molecular structure is shown below:
