Technical Data
Histamine is a neurotransmitter in the central nervous system a well as a mast cell constituent. In addition, histamine is produced by endocrine cells (ECL-cells) in the oxynthic mucosa of the stomach.

Suitable for use in Immunohistochemistry and Immunofluorescence. Other applications not tested.

Recommended Dilutions:
Immunohistochemistry (Frozen and paraffin sections): 1:1500-1:2000 (PAP).
Immunofluorescence: 1:300-1:600 with overnight incubation at 4C.
Optimal dilutions to be determined by the researcher.

Recommended Positive Control:
Cryostat sections of carbodiimide fixed human skin or freeze-dried paraffin-sections (vapor fixed in diethylpyrocarbonate; DEPC) of rat stomach.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months after receipt at -20C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Histamine, conjugated to HSA
Supplied as a lyophilized powder. Reconstitute with 50ul sterile ddH2O Further dilutions should be made in PBS, 1% BSA, 0.09% sodium azide.
Recognizes Histamine. Absorption with 10-100ug histamine per ml diluted antiserum abolishes the staining, while noradrenaline, 5-HT, VIP, glucagon and histidine do not. Species Crossreactivity: human and rat
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
