The picro sirius red staining technique is frequently used to histologically stain collagen I and III fibers. This kit can be used to identify fibrillar collagen networks in tissue sections.
When viewed under linear polarized light, collagens appear as green, red, orange or yellow fibers.
Sample orientation under linear polarized light is thought to affect the hue and signal strength of the technique. Circular polarized light may be used to overcome this limitation but requires specialized equipment. Alternatively, fluorescent imaging of picro sirius red stained samples may be used which yields a strong red fluorescent signal that is sensitive and specific for collagen and is unaffected by sample orientation.
