Picro-Sirius Red Stain Kit (Cardiac Muscle)

Picro-Sirius Red Stain Kit (Cardiac Muscle) ab245887 is intended for use in the histological visualization of thin septa and collagen fibers. This modification of the Picro-Sirius Red stain eliminates the yellow cytoplasmic staining that can obscure thin collagenous septa. Using this procedure easily allows viewing of collagenous septa as thin as 0.2-0.5 microns. The PSR stain may be viewed using standard light microscopy or polarized light resulting in birefringence of the collagen fibers. **Light Microscopy** Collagen: Red Septa: Red Cytoplasm: Colorless to Slightly Yellow **Polarized Light Microscopy** Collagen: Yellow-Orange and Green Birefringence **Control Tissue:** Cardiac Muscle Uterus Lung Kidney. **Other products for staining tissue sections** Find more kits and reagents in the , or products for antigen retrieval, blocking, signal amplification, visualization, counterstaining, and mounting in the . **ab245887 may not be suitable with frozen sections.**
