Application Abreviews Notes
WB 1/1000. when using colorimetric substrates such as BCIP/NBT and 1/5000 for chemiluminescent substrates. Predicted molecular weight: 150 kDa. Dilution optimised using Chromogenic detection
IHC-P 1/500. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.


  • Function
    Converts angiotensin I to angiotensin II by release of the terminal His-Leu, this results in an increase of the vasoconstrictor activity of angiotensin. Also able to inactivate bradykinin, a potent vasodilator. Has also a glycosidase activity which releases GPI-anchored proteins from the membrane by cleaving the mannose linkage in the GPI moiety.
  • Tissue specificity
    Ubiquitously expressed, with highest levels in lung, kidney, heart, gastrointestinal system and prostate. Isoform Testis-specific is expressed in spermatocytes and adult testis.
  • Involvement in disease
    Ischemic stroke (ISCHSTR) [MIM:601367]: A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
    Renal tubular dysgenesis (RTD) [MIM:267430]: Autosomal recessive severe disorder of renal tubular development characterized by persistent fetal anuria and perinatal death, probably due to pulmonary hypoplasia from early-onset oligohydramnios (the Potter phenotype). Note=The disease is caused by mutations affecting the gene represented in this entry.
    Microvascular complications of diabetes 3 (MVCD3) [MIM:612624]: Pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
    Intracerebral hemorrhage (ICH) [MIM:614519]: A pathological condition characterized by bleeding into one or both cerebral hemispheres including the basal ganglia and the cerebral cortex. It is often associated with hypertension and craniocerebral trauma. Intracerebral bleeding is a common cause of stroke. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.

    Tissue was fixed in paraformaldehyde and a heat mediated antigen retrieval step was performed using TRIS pH 9.0, 123°C for 1 minute. Samples were then permeabilized using 0.1% Triton, blocked with 3% BSA for 30 minutes at 25°C and then incubated with ab28311 at a 1/500 dilution for 16 hours at 4°C. The secondary used was an undiluted goat anti-rabbit polyclonal-HRP.

Thank you for your telephone call earlier today. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.

As discussed on the phone, I can confirm that ab28311 is tested and covered by our guarantee in WB and human samples. In and in the event that a product is not functioning in the applications cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund.

I would like to investigate this particular case further for you, and also obtain more information for our quality monitoringrecords. In order to proceed with this, I have enclosed atechnical questionnaire below. I would appreciate if you could complete this. It will help you put the information we require together very easily.

With regards to the positive controls, Angiotensin Converting Enzyme 1 is known to be highly expressed in lung, kidney and heart tissue. We do havesomelysated available in our catalog:

ab29118 Lung: right lower lobe (Human) Whole Cell Lysate - adult normal tissue (or use the following:

ab30203 Kidney (Human) Tissue Lysate - adult normal tissue (or use the following:
