Endomorphin-2
(Cat #:MV1007)
| Rabbit polyclonal antibody to synthetic Endomorphin-2 |
 Immunohistochemical staining of Endomorphin 2 in rat ventral lateral periaqueductal grey matter (PAG). 4% paraformaldehyde fixed rat brain 10 μm thick cryostat sections were incubated with rabbit polyclonal antibody to Endomorphin 2 at 10 μg/mL overnight at 4°C followed by incubation with Donkey anti-rabbit Rhodamine Red conjugated secondary antibodies at 1:200. Tissue was counterstained with DAPI (blue color) to visualize cell nuclei. |
| Formulation |

| Unit Size: |
50 µg |
| Immunogen |
Endomorphin-1 conjugated to BSA. |
| Sequence: |
YPFF |
| Antigen Location (aa): |
1-4 |
| Alternative Names |
N/A |
| Accession Number: |
Precursor protein is not identified. |
| Accession Name: |
Precursor protein is not identified. |
| Accession URL: |
Precursor protein is not identified. |
| Function: |
Human; mouse; rat. Endomorphin-1 a highly conserved molecule, so cross-reactivity with other species is expected. Cross-reactivity with other opioid peptides is as follows: with Endomorphin-1 < 3%; Met-enkephalin <0.03%; with Leu-enkephalin 0.01%; with beta-endorphin<0.1% |
| Applications: |
Recommended for Immunohistochemistry (IHC) and Cytochemistry (ICC). |
| 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, DRG). |
| Specificity: |
Confirmed by RIA against the synthetic peptide. |
| Cross-reactivity: |
Human; mouse; rat. Endomorphin-1 a highly conserved molecule, so cross-reactivity with other species is expected. Cross-reactivity with other opioid peptides is as follows: with Endomorphin-2 <5%; Met-enkephalin <0.03%; with Leu-enkephalin 0.01%; with beta-endorphin<0.1% |
| 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. |
