There are variations in the way it's done, but the classical
paper is probably Sweat F, Puchtler H & Rosenthal S
(1964) Sirius red F3BA as a stain for connective tissue.
Arch. Pathol. 78: 69-72. The method you are using may not, of
course, be exactly the same. The most thorough study of this useful
technique is probably by Junqueira et al. (1979) Histochem. J.
11: 447-455. Among other things, they showed that staining of
collagen occurred slowly (in contrast to va Gieson's method),
needing the best part of an hour. (It's a good investment of
time because sirius red it shows thin fibres and basal laminae
that Van Gieson's misses, and there's also the beautiful
enhancement of birefringence of Type 1 collagen fibres.)
