    • Relevance

      Macrophages comprise of many forms of mononuclear phagocytes found in tissues. Mononuclear phagocytes arise from hematopoietic stem cells in the bone marrow. After passing through the monoblast and promonocyte states of the monocyte stage, they enter the blood, where they circulate for about 40 hours. They then enter tissues and increase in size, phagocytic activity, and lysosomal enzyme content becomming macrophages. Among the functions of macrophages are nonspecific phagocytosis and pinocytosis, specific phagocytosis of opsonized microorganisms mediated by Fc receptors and complement receptors, killing of ingested microorganisms, digestion and presentation of antigens to T and B lymphocytes, and secretion of a large number of diverse products, including many enzymes including lysozyme and collagenases, several complement components and coagulation factors, some prostaglandins and leukotrienes, and many regulatory molecules (Interferon, Interleukin 1). Among cells that are now recognised as macrophages are histiocytes, Kupffer cells, osteoclasts, microglial cells, synovial type A cells, interdigitating cells, and Langerhans cells (in normal tissues) and epithelioid cells and Langerhans-type and foreign-body-type multinucleated giant cells (in inflamed tissues).

    Thank you for contacting Abcam.

    The expected band size is around 150kDA. I am sorry to hear of the difficulties that you have been experiencing using these products. Would you mind sending me the details of your protocol including the tissue type you are working with, your sample preparations including denaturing and reducing steps, the amount of total protein per well, the positive controls you have used, loading controls or poncheau staining results, blocking procedures, antibody incubation steps, washes, images and any steps that you may have changes while troubleshooting.

    These details will not only help me to better understand your difficulties and be able to offer suggestions but will also be used for internal testing of the products if deemed necessary. If we are unable to solve the problems you are experiencing we will replace or refund the antibody according to our Abpromise guarantee.
