Target

  • Tissue specificity

    Strong expression in kidney and heart, and lower in liver and skeletal muscle.

  • Pathway

    Lipid metabolism; fatty acid beta-oxidation.

  • Involvement in disease

    Defects in CPT1A are the cause of carnitine palmitoyltransferase 1A deficiency (CPT1AD) [MIM:255120]; also known as CPT-I deficiency or CPT1A deficiency. CPT1AD is a rare autosomal recessive metabolic disorder of long-chain fatty acid oxidation characterized by severe episodes of hypoketotic hypoglycemia usually occurring after fasting or illness. Onset is in infancy or early childhood.

  • Sequence similarities

    Belongs to the carnitine/choline acetyltransferase family.

  • Cellular localization

    Mitochondrion outer membrane.

    IHC image of CPT1A staining in human normal kidney formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab128568, 0.5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Question

I've done many mitochondria isolation in liver and it works. So, I just wanted to know if there is a difference in mitochondria isolation in the heart.
.com

Read More
Answer

Hello. I have contacted the laboratory regarding differences between mitchondria isolation in the heart and they have said there is not many differences. Mitochondria preparations are typically better from the heart (purer and higher yield).Heart contains about 30% mitochondria to begin with. Dissection and homogenization are critical because the muscle is not a soft tissue. Buffers are the same. Please let me know if I can be of further assistance.
