Target

  • Function
    The primary function of this lipase is the hydrolysis of triglycerides of circulating chylomicrons and very low density lipoproteins (VLDL). Binding to heparin sulfate proteogylcans at the cell surface is vital to the function. The apolipoprotein, APOC2, acts as a coactivator of LPL activity in the presence of lipids on the luminal surface of vascular endothelium.
  • Involvement in disease
    Defects in LPL are the cause of lipoprotein lipase deficiency (LPL deficiency) [MIM:238600]; also known as familial chylomicronemia or hyperlipoproteinemia type I. LPL deficiency chylomicronemia is a recessive disorder usually manifesting in childhood. On a normal diet, patients often present with abdominal pain, hepatosplenomegaly, lipemia retinalis, eruptive xanthomata, and massive hypertriglyceridemia, sometimes complicated with acute pancreatitis.
  • Sequence similarities
    Belongs to the AB hydrolase superfamily. Lipase family.
    Contains 1 PLAT domain.
  • Post-translational
    modifications
    Tyrosine nitration after lipopolysaccharide (LPS) challenge down-regulates the lipase activity.
  • Cellular localization
    Cell membrane. Secreted. Locates to the plasma membrane of microvilli of hepatocytes with triacyl-glycerol-rich lipoproteins (TRL). Some of the bound LPL is then internalized and located inside non-coated endocytic vesicles.

  • ab21356 staining Lipoprotein lipase in Mouse small intestine tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 1.5% serum for 30 minutes at 23°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (2 ug/ml) for 14 hours at 4°C. A Biotin-conjugated Goat anti-mouse IgG polyclonal (1/200) was used as the secondary antibody.

The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab21356, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Answer

This antibody was raised against the whole Human LPL whole protein as stated in the datasheet.

Unfortunately, the exact epitope is unknown as the whole protein with all regions intact was used to produce the antibody and the epitope has not been mapped.

Answer

Thank you for your reply and for keeping me updated.

I am glad to hear that some bands were seen on the membrane, but I am sorry that it took such a high concentration in order to work in this assay. I have only been able to get the QC data for the first lot that you used, which is attached to this email. The left lane shows human LPL and the right lane shows bovine LPL. The QC data for the new lot is not available at this time.

Which secondary antibody did not work? I will be happy to refund or replace this antibody if you would like.

I look forward to hearing from you. Please let me know if you have further questions or if there is anything else that we can do.

Answer

Thank youagain for letting us know about the trouble with this antibody.

Have you had a chance to try the replacement vial of ab21356 from a new lot, or done any other testing?

I have received the QC data from the lab for the first lot that you tried, but the QC data for the new lot is unfortunately not available. Please see the data attached. Lane 1 is human LPL and lane 2 is bovine LPL.

I look forward to hearing from you. If there is anything else that we can do for you please let me know.
