Enkephalins (penta-peptides) have been discovered as regulators of nerve impulses involving pain in the brain. It has been shown that these peptides act as natural analgesics (pain-killers) and their action mimics that of morphine and other opiates. At present, it is thought that the morphine-like effects are due to aromatic side chains on phenylanine and tyrosine which mimic a similar structure on morphine. Research suggests that it does not make much difference whether the enkephalin contains methionine or leucine at the acid end of the peptide for its action.

Lyophilized tissue culture supernatant
Recommend starting dilution:
If reconstituted with deionized water in 200 µL: IHC / ICC 1:200 - 1:800. Optimal dilution has to be determined by the user.
Lyophilized antibodies can be kept at 4ºC for up to 3 months and should be kept at -20ºC for long-term storage (2 years). To avoid freeze-thaw cycles, reconstituted antibodies should be aliquoted before freezing for long-term (1 year) storage (-80ºC) or kept at 4ºC for short-term usage (2 months). For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made with the assay buffer. After the maximum long-term storage period (2 years lyophilized or 1 year reconstituted) antibodies should be tested in your assay with a standard sample to verify if you have noticed any decrease in their efficacy.
