C17H12N2O7S3Na2 F.W. 498.50 CAS #5-1023-76-8
SITS has been used as a vital stain, as a label for immunostaining, and as a neuronal tracer. SITS is also a non-penetrating fluorescent marker for erythrocyte membranes which acts as a potent inhibitor of anion transport. For more information related to the preparation and characterization of SITS, please refer to: Jakobsen, P. and Horobin, Richard W.(1989). Stain Technology, Vol.64, No.6 pg.301-313.

Bismuth Stain Kit铋染色试剂盒
Bismuth specifically stains Golgi beads and interchromatin granules after fixation with glutaraldehyde, whereas it stains nucleoli, basic protein, and biogenic amines after formaldehyde fixation. Bismuth staining of sections is relatively nonspecific: it can stain glycogen, lysosomes, ribosomes, polysaccharides, ferritin, and DNA. M.A. Hayat, "Basic Techniques for TEM" p. 184 (1986).
