Flow Fix, 2% Paraformaldehyde Fixative KitCatalog Number 25085
Flow Fix, 2% Paraformaldehyde Fixation Buffer is a sodium azide free buffer comprised of a neutral pH-buffered saline (i.e., Dulbecco's Phosphate-Buffered Saline) that contains 2% w/v paraformaldehyde. Sodium Azide –Free. Do not add sodium azide to buffers if you are concerned with recovering cell function.
-
ParaformaldehydeCatalog Number 00380
Paraformaldehyde depolymerizes in water to formaldehyde solution yielding consistent quality fixative solutions. To achieve a strong solution, raise the temperature of the water to 60ºC then add sodium hydroxide solution dropwise.
-
Hollande's FixativeCatalog Number 24354
Hollandes fixative is excellent for large and small gastric tissue, GI biopsies or any tissues that contain large amounts of inflammatory and mucinous cells. This solution is one of the best fixatives for certain kinds of protozoa.
-
Formalin, 10% neutral buffered (phosphate buffer)Catalog Number 08379
Widely used fixative for processing tissues in routine histology laboratories. Used for IHC in the clinical laboratory for paraffin embedded tissues.
Volume of the fixative should be 15-20 times that of the tissue.
(Formaldehyde 3.7%)
