Description

General description

Histamine dihydrochloride is a derivative of histamine. It prevents the formation of ROS (reactive oxygen species), which inhibits the activation of T cells and natural killer cells. Histamine dihydrochloride is implicated in tumor cell apoptosis. It prevents the relapse of acute myeloid leukemia in patients.

Application

Histamine dihydrochloride has been used:
• as a orthograde cotransmitter in producing excitatory postsynaptic potential (EPSP)
• to determine its level in fish using HPLC (high performance liquid chromatography)
• to assess the tracheal response to antigens in guinea-pigs

Frequently Asked Questions

How does the storage temperature relate to shipping conditions?
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
How do I find price and availability?
There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.
