Leu-Enkephalin
(Cat #: MV1009)
| Product Description |
Rabbit polyclonal antibody to human Met-Enkephalin |
 Immunohistochemical detection of Leu-Enkephalin in rat ventral periaqueductal grey matter (PAG). Brain was fixed with 4% formaldehyde and cut into 10 μm thick cryostat sections. Tissue was incubated with rabbit polyclonal antibody to Leu-Enkephalin at 10 μg/mL overnight at 4°C followed by incubation with Donkey anti-rabbit Rhodamine Red (pseudo-coloured yellow) conjugated secondary antibodies at 1:200. Tissue was counterstained with DAPI (blue color) to visualize cell nuclei. |

| Function: |
Leu-Enkephalin is an endogenous opioid peptide that interacts with opioid receptors and produces analgesic effects. |
| Applications: |
Recommended for Immunohistochemistry (IHC), Cytochemistry (ICC) and RIA. |
| Working Dilution for Immunofluorescence (ICC): |
5 – 15 µg/mL |
| Working Dilution for Immunohistochemistry (IHC): |
5 – 10 µg/mL |
| IHC Positive control: |
Brain (spinal cord, PAG). |
| Specificity: |
Confirmed by RIA against the synthetic peptide. |
| Cross-reactivity: |
Human; mouse; rat. Leu-Enkephalin is a highly conserved molecule, 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%. |
| Reconstitution: |
Reconstitute in 0.05 mL of PBS (pH 7.4) to achieve an antibody concentration of 1000 µg/mL. Centrifuge to remove any insoluble material. |
| Storage / Stability: |
At least 12 months after purchase at 2 - 4°C. After reconstitution, aliquot and store at -20°C for a higher stability and at 4°C with an appropriate antibacterial agent. Avoid freeze-thaw cycles. |
