      The endothelium is located at the interface between the blood and the vessel wall. The cells are in close contact and form a slick layer that prevents blood cell interaction with the vessel wall as blood moves through the vessel lumen. The endothelium consists of simple squamous epithelium that lines the lumen of all blood vessels. It plays a critical role in the mechanics of blood flow, the regulation of coagulation, leukocyte adhesion, and vascular smooth muscle cell growth, and also serves as a barrier to the transvascular diffusion of liquids and solutes. For years the endothelium was thought of as an inert single layer of cells that passively allow the passage of water and other small molecules across the vessel wall. However, this dynamic tissue performs many other active functions, such as the secretion and modification of vasoactive substances and the contraction and relaxation of vascular smooth muscle.

    Thank you for contacting us and your interest in our products.
    As you have seen from the datasheet of the anti-Endothelium antibody [PAL-E] (ab8086), the antibody has not as yet been used in detecting the ovine protein or IHC of paraffin embedded sections as you are hoping to do. This does not mean that it would not work, simply that we have not had any reports supporting it yet.
    Unfortunately we are not able to provide sample sizes of any of our products. This is due to the logistics that would be involved in this, with such a large catalogue this simply isn't feasible. However, we do offer a testing discount scheme. This offer means that if you test the antibody with ovine paraffin embedded tissue and share the results with us through an Abreview (no matter whether positive or negative) you would be eligible for a free primary antibody of your choice from our catalogue (or the equivalent price off any product in our catalogue). More information on this offer can be found here:
    The only constraint to this offer is that the antibody to be tested must be purchased, tested, the Abreview submitted and the free primary antibody claimed within a 4 month period.
    If you would be interested in participating in this scheme please do let me know as a discount code needs to be issued prior to the purchase of ab8086.
    I hope this information has been of help. If you require any further information please do not hesitate to contact us again.
