Dynorphin A
Description:
Leu-enkephalins compete with and mimic the effects of opiate drugs. They play a role in a number of physiologic functions, including pain perception and responses to stress. Dynorphin peptides differentially regulate the kappa opioid receptor. Dynorphin A(1-13) has a typical opiod activity, it is 700 times more potent than Leu-enkephalin.
Cells are found in the paraventricular and supraoptic nucleus and fibers are found in the lateral hypothalamus in rat brain of 4% FA perfused colchicine tissue.

Applications:
Suitable for use in RID and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
RID: 1:10,000
Immunohistochemistry (Paraffin): Requires antigen retrieval using heat treatment prior to staining. Sodium citrate buffer, pH 6.0, is recommended. Overnight incubation recommended.
Immunohistochemistry (Frozen): 1:100-1:500
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
