Red blood cells begin as immature cells in the bone marrow and after approximately seven days of maturation are released into the bloodstream. Unlike other cells, red blood cells have no nucleus and can easily change shape, in order to constrict and pass through narrow capillaries throughout the body. Lack of a nucleus makes a red blood cell more flexible but also limits the life of the cell as it travels through the body suffering damage to its membranes and depleting its energy supplies. The red blood cell survives on average 120 days.
Red cells contain a protein called haemoglobin, which carries oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs to be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the haemoglobin.
Compared to other species, horse red cells have a marked tendency to form rouleaux, or stacking.
Fitzgerald Industries supplies high quality, glutaraldehyde-stabilized freshly prepared Horse Red Blood Cells for research purposes. Exposure to glutaraldehyde buffer has preserved the native antigenicity of the cells and increased their stability. We also supply equine Red Blood Cell antibodies such as a rabbit polyclonal Horse RBC antibody, which is also available in Horse RBC antibody (FITC) and Horse RBC antibody (Texas Red) conjugated formats for use in FACS and fluorescence based applications.
