Anti-CD13 抗体 [WM15] (ab7417)

Thank you for your reply.
I cannot recommend this antibody for your purposes. Rat still shows a 77% homology and I am afraid that this could be boarder line and this antibody might cross-react.
It is always very difficult to positively proof that an antibody does not react with a certain species. If we do know this we will mention this on our datasheets in form of a "does not react" note. This indicated that the antibody was experimentally tested not to cross-react.
I attached a list of all our antibodies that react with human but do not react with rat for your information.
Maybe this list will include a suitable antibody for your purposes?
Please feel free to contact me again with any further questions.

Thank you for your inquiry.
This antibody is tested and guaranteed to work with human samples. Other species were not experimentally tested by us and we simply do not know i this antibody will cross-react.
Human CD13 show a high homology with CD13 of Gorilla and of non human primates (greater than 85%) and therefore it is very likely that this antibody will cross-react. I attached a overview to this email for your information.
If you are interested in using ab7417 with a species that shows 85% or more homology you might be eligible for our testing discount program.
I hope this information is helpful.
Please do not hesitate to contact me again with any further questions about ab7417 or the testing discount program.

Thank you for your enquiry. The best choice for a lysate would be a membrane fraction lysate, not a nuclear lysate, since CD13 is a trans-membrane protein. The antigen is expressed on a variety of tissues. The best choice is ab7913, THP1 (Human acute monocytic leukemia cell line) Whole Cell Lysate: https://www.abcam.com/THP1-whole-cell-lysate-ab7913.html We do not have a membrane fraction lysate for this cell line but this preparation will serve as well. Other tissue lysates that could work as positive controls are suggested by the SwissProt entry (accession number P15144) for CD13: "TISSUE SPECIFICITY: Expressed in epithelial cells of the kidney, intestine, and respiratory tract; granulocytes, monocytes, fibroblasts, endothelial cells, cerebral pericytes at the blood-brain barrier, synaptic membranes of cells in the CNS. Also expressed in endometrial stromal cells, but not in the endometrial glandular cells. Found in the vasculature of tissues that undergo angiogenesis and in malignant gliomas and lymph node metastases from multiple tumor types but not in blood vessels of normal tissues. A soluble form has been found in plasma. It is found to be elevated in plasma and effusions of cancer patients." I hope this helps.
