Study ID	ST001434
Study Title	Untargeted lipidomics of liver to assess the potential protective role in atherosclerosis progression of A12 antibodies infusion into LDLR-/-mice
Study Type	LC-MS Untargeted Lipidomics
Study Summary	In order to assess the therapeutic potential of A12 antibodies in atherosclerosis, untargeted lipidomics of liver samples was performed. LDLR-/-mice were treated with a fully murine version of the A12 antibody (mA12-IgG2b), with the isotype control antibody mB1.8-IgG2b (n=16) or with PBS as controls.

Sample Preparation:

Sampleprep ID:	SP001516
Sampleprep Summary:	Frozen liver tissues were lysed in 0.5X PBS (sample:solvent 1:10 ratio) containing 1 mg/mL butylhydroxytoluene (BHT) solution in methanol (proportion 200 µL per g of tissue), with FastPrep-24 5G instrument (MP Biomedicals, USA). 25 µL aliquots of homogenate were collected and stored at -80°C until lipidomic extraction. Tissue homogenates were thawed and extracted with methyl-tert-butylether (MTBE) as described in [Matyash, V., et al., Lipid extraction by methyl-tert-butyl ether for high-throughput lipidomics. Journal of lipid research, 2008. 49(5): p. 1137-46]. 900 µL of organic phase were dried-out in speedvac and resuspended in 50 µL of ACN:H2O (20:80, v:v) just before injection.
