UltimateSPLASH™ ONE ONE internal standard for lipidomic analysis Product number 330820

UltimateSPLASH™ ONE was created to address the need for a comprehensive set of internal standards and greatly expands the number of chain length and unsaturation variants within a given class, which may be used to control for differences in ionization and fragmentation efficiency. These internal standards are intentionally designed to appear in the spectral gaps between naturally occurring lipid species, and their relative abundances have been varied to reflect the patterns found in nature. Additionally, UltimateSPLASH™ incorporates these features into more lipid classes than ever before; PI, PS, PG, LPI, LPS, and LPG are now included for even broader lipidomics applications. The resulting final mixture contains a total of 69 unique and highly pure lipids across 15 lipid classes, which have been meticulously characterized, quantitated, and blended for accurate quantitation using multiple lipidomics-workflows.

Lipids comprise an amazingly complex and diverse set of molecules that are involved in numerous biological processes including energy storage/release, signaling, growth, disease, and death. Over the last 20 years, use of soft ionization techniques in conjunction with single and multistage mass spectrometry both with and without prior separations have enabled unprecedented levels of sensitivity, speed, and specificity for identification, structure determination, and quantitation of these highly diverse ensemble of molecules. However, one of the primary challenges that remained was the development of a comprehensive set of internal standards which would allow accurate quantitation of numerous individual molecular species.

MSI SPLASH ™ Product number 330841

As the role of lipids in neurodegenerative diseases such as Parkinson’s Disease is increasingly acknowledged, it has become essential to consider what lipids may have a hand in neuropathology. MSI SPLASH is made specifically for Mass Spec Imaging of neurological tissue. The mixture of thirteen internal standards is designed to be applied to brain sections using a sprayer, similarly to the application of matrix for MALDI. MSI SPLASH allows not only for quantitation of lipids within the brain, but also localization of those lipids to provide more detailed information for answering biological questions. This mixture was designed in collaboration with Michiel Vandenbosch, Shadrack Mutuku, Shane Ellis & Kim Ekroos. Toward Omics-Scale Quantitative Mass Spectrometry Imaging of Lipids in Brain Tissue Using a Multiclass Internal Standard Mixture. Michiel Vandenbosch, Shadrack M. Mutuku, Maria José Q.

Frequently asked questions

How do I handle Avanti Mass Spec Standards properly? Your Avanti Mass Spec Standard should be stored in a -10°C to -25°C freezer until ready for use. It is designed to be a one-time use ampule, and we do not recommend extended storage after opening. Always make sure to warm bath sonicate the unopened ampoule for approximately 2 minutes prior to opening the ampoule. Lipids in solution may precipitate during shipping and storage conditions, and it may not be visible with a solution at extremely low concentrations such as this. Directly transfer from ampule to sample preparation glass vial for immediate use. General handling guidelines for lipids should be followed as outlined on our website. How do I order Avanti Mass Spec Standards? Please visit the Avanti website. Customers in the United States can order directly from Avanti, and customers outside the United States will be directed to our worldwide distribution partner for country specific ordering information and pricing. Can I use my Avanti Mass Spec Standard more than once? Avanti quantitative mass spectrometry standards are designed to be “one-time use” items. It is important to directly transfer from the ampule to the experiment or prepare as a dilution for immediate use. Avanti cannot guarantee product purity and subsequent performance if used outside these guidelines. How do I reference an Avanti Mass Spec Standard in my publication? Please list the full name and product number of the Avanti product in your materials and methods sections, along with “Avanti Polar Lipids, Alabaster, AL” as the source. If you publish using an Avanti product we would love to hear about it! Please drop us an email and share your success stories.

How do I open the sealed glass ampule? Ampules are pre-scored for easy opening. With the ampule upright, hold the ampule in a gloved hand and firmly push the top section away from you with even pressure. The top should cleanly snap off, but proceed with care, as it will leave a sharp glass edge. Can I get a Custom Mass Spec Standard? Yes, we custom formulate mass spec standards using the lipids and solvents of your choice. We work with you to design your custom mass spec standard and can make recommendations if needed. Let us know how we can help by emailing lipidomics@avantilipids.com.

Bile acids Bile acids are potent digestive surfactants which promote the absorption of lipids. They also represent the primary pathway for cholesterol catabolism and account for approximately 50% of the daily turnover of cholesterol 2 . However, bile acids are no longer limited to solely that. Bile acids have now been recognized as hormones involved in the regulation of various metabolic processes. Bile acids regulate not only their own synthesis and enterohepatic circulation, but also triglyceride, cholesterol, glucose and energy homeostasis. Current metabolomic and lipidomic efforts aim to provide new insights into the mechanism of bile acid signaling in the regulation of lipid metabolism and the maintenance of lipid homeostasis. 1,2 Avanti’s comprehensive line of pure bile acid primary standards and internal standards are the perfect complement to primary, secondary, and/or conjugated bile acid research in any clinical, toxicology, or research laboratory. The table is just a sample of the many bile acid standards that Avanti offers. Visit the website links below to discover the full lineup.

IsoPure Phospholipids Mixed-acyl glycerophospholipids are among the most abundant lipids in nature. Famously, 1-palmitoyl-2-oleoyl phosphatidylcholine (POPC) is the most abundant phospholipid in most eukaryotic cells and tissues. The molecular structure of POPC follows the textbook consensus that unsaturated fatty acyl chains occupy the sn-2 position of the glycerol backbone while saturated fatty acyl chains are relegated to the sn-1 position. As our analytical technologies advance, this conventional wisdom is being turned inside out with the isomer 1-oleoyl-2-palmitoyl phosphatidylcholine (OPPC) being identified at high abundance in samples ranging from plasma to tissue 1,2,3 . Adding to the complexity, both isomers are present in many instances in ratios ranging from 1:100 to 1:1. Resolving the puzzle of lipid isomers requires advanced analytical tools in conjunction with structurally defined reference materials. Until recently, commercially available synthetic lipids were also comprised of mixtures, as transacylation occurring in the round-bottom flask always led to 10-20% OPPC in any preparation of POPC. Moreover, the regiopurity of the product was difficult to define. Avanti has now introduced the IsoPure line wherein innovative synthetic procedures produce mixed-acyl glycerophospholipids with >99% regiopurity. These next-generation standards will be pivotal to isomer-resolved identification of glycerophospholipids in biological samples. 1 Ekroos K, Ejsing CS, Bahr U, Karas M, Simons K, Shevchenko A.
