SMA Universal with pH-Selector Cat. No. #IAX-700-205

• A nanoparticle (11-40nm) drug delivery system comprising a discoidal phospholipid bilayer • membrane stabilised by a chaperone molecular annulus.

• All components are batch tested for Lipodisq™ formation using validated buffer systems, which are assessed by Dynamic Light Scattering (DLS) to confirm nano-formulated drug characteristics. The buffer solutions themselves are endotoxin tested and supplied sterile.

• Lipodisq™ formation is highly efficient and shows a good safety profile, suitable for in vitro and in vivo (in experimental animals) investigations.

Enables membrane proteins (MP) to be reconstituted within phospholipid membrane mimics
without the use of mediating detergent. Nanodiscs formed from SMA are also referred to as styrene
maleic acid lipid particles (SMALP). SMA-lipid particles are formed by directly extracting membrane
proteins either from native cellular membranes (giving native nanodiscs) or from an intermediary
MP-reconstituted synthetic membrane system to ultimately form self-assembled discoidal nano-structures
of a general diameter of 10–12 nm.
• uSMA requires only a single polymer grade to be used, avoids the need to select several SMA
grades that each operate only over a narrow pH range
• uSMA can be tailored to operate over a wide pH range 4.5-8.5 by simple addition of standard
quantities of pH-Selector™
• uSMA is insensitive to presence of divalent cations, Ca2+(<10mM) and Mg2+ (<30mM),
suitable for use with ion pores, ABC transporters and ion sensitive GPCR assemblies
• uSMA can be modified to form larger particles, reducing direct interactions between the polymer
chaperone and membrane‑bound proteins
The ability of SMA to create monodisperse nanodiscs covering a range of particle sizes facilitates
the reconstitution of oligomeric MPs and MP complexes for analysis by various methods including
fluorescence microscopy, NMR and single-particle cryo-EM. Lipodisq™ technology is a proprietary
technology developed by Malvern Cosmeceutics Limited and is subject to granted international patents.

100mg size includes 0.5ml pH-SelectorTM and 500mg size includes 2.5ml pH-SelectorTM

MW

Polymer MW average: MW: 5,500  MW: MW based on weight / MN: 2,100  MN: MW based on number

Purity

>98%

Solution pH

4.5 to 8.5 in 5% ddWater depending upon the addition of pH-SelectorTM

Solubility

Soluble in water, and buffer solutions (pH 4.50-8.50) to allow the formulation of a proprietary, thermostable, aqueous lipid nanoparticle (LipodisqTM, Malvern Cosmeceutics Ltd., Malvern UK). uSMA with pH-SelectorTM has overcome the limitations using divalent ions or narrow, defined pH ranges usually an inherent property of P(SMA), which can cause P(SMA) precipitation or interfere with SMA-Lipid Particle formulation or stability. Compatible with Ca++ (10mM) or Mg++ (30mM).

Formulation with
Phospholipids

LipodisqTM are nanosized lipid-based discoidal particles that can be produced with P(SMA)and lipids such as DMPC (1,2-Dimyristoyl-sn-glycero-3-phosphocholine) (14:0 PC) (DMPC: IAX-700-400) to incorporate hydrophobic, poorly water-soluble active compounds, such as peptides, lipids, lipoproteins, transmembrane proteins and glycolipids. Applications of LipodisqTM include functional and structural characterisation of the embedded cargo, drug delivery with enhanced bioavailability, or extended biological half-life in vivo (PD/PK) and delivery of antigens maintained in their native conformation for immunization purposes.

Appearance

White powder

Handling

Keep dry. Avoid skin and eye contact.

Shipping

Ambient

Storage

2-8°C or 15-25°C

Stability

Upon receipt, store product at ambient temperature. Freezing is not recommended. In its unopened original vial, the product is stable for at least 36 months when stored at ambient temperature. Once the glass vial is opened, or solubilized in sterile, endotoxin-free ddWater (IAX-900-902) or in pH-SelectorTM or buffers and aliquoted into sterile vials under sterile conditions, the SMA polymer solution (e.g. at 5%) remains stable for at least 1 month when stored at 2-8°C and kept sterile.


LipodisqTM Technology
  • A nanoparticle (11-40nm) drug delivery system comprising a discoidal phospholipid bilayer membrane stabilised by a chaperone molecule annulus.

  • Internal properties of the phospholipid membrane support the disposition and stabilisation of drug molecule candidates and preserve the native conformation of membrane molecules.

  • The resulting encapsulated actives are rendered water-soluble and specialised for intra-cellular penetration/delivery via endosomal uptake mechanisms.

  • LipodisqTM solutions show a good safety profile and are suitable for in vitro and in vivo investigations.

  • For a customizable biodegradable LipodisqTM version with a higher concentration of actives or an alternative lipid option, contact Innaxon.
