Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting. It is usually thinner than collagen fibers. VitroViewTM Verhoeff-Van Gieson Elastin Stain Kit is used for identifying elastic fibers in tissues such as skin, aorta, etc. on formalin-fixed, paraffin-embedded sections, and may be used for frozen sections as well. The elastic fibers will be stained blue-black and background will be stained yellow.Kit Contents (A printed user manual is included)VB-3019-1 Alcoholic Hematoxylin 100mlVB-3019-2 10% Ferric Chloride Solution 100mlVB-3019-3 Weigert’s Iodine Solution 100ml VB-3019-4 5% Sodium Thiosulfate Solution 100mlVB-3019-5 Van Gieson’s Solution 100ml
