SpecificityHuman; mouse; rat. Leu-Enkephalin is highly conserved so cross-reactivity with other species is expected. Cross-reactivity with other opioid peptides is as follows: with Met-enkephalin 0.93%; with beta-lipotropin 0.01%; with beta-endorphin 0.01%
Species ReactivityHuman, Mouse, Rat
Immunogen DescriptionSynthetic human Leu-Enkephalin peptide (230 - 234) conjugated to BSA.
Application DetailsA dilution of 5-10 µg/mL is recommended for immunohistochemistry using formalin fixed and paraffin embedded tissues and for 4% paraformaldehyde fixed frozen tissues. A dilution of 5-15 µg/mL is recommended for immunofluorescence. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Scientific BackgroundLeu-Enkephalin is cleaved from the precursor Proenkephalin-A. Leu-Enkephalin is an endogenous opioid peptide that interacts with opioid receptors and produces analgesic effects.
Immunohistochemical staining in rat spinal cord dorsal horn. 4% paraformaldehyde fixed rat brain crystostat sections (10 µm) were incubated overnight at 4°C with Rabbit polyclonal antibody to human Leu-Enkephalin (10 µg/mL) followed by incubation with donkey anti-rabbit Rhodamine Red conjugated secondary antibody (1:200).
