||Endomorphins 1 and 2 are endogenous opioid peptides which have the highest affinity for the mu-opioid receptors. Located in various parts of the brain and interacts with mu-opioid receptors and produces analgesia.
||See product label
||Antibodies to human Endomorphins 1 and 2 were made by immunising rabbits with the human Endomorphin-1 peptide (YPWF) and then selecting those antibodies that cross-reacted with both human Endomorphins 1 and 2.
||EM 1; EM 2;
||A 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.
||Human; mouse; rat. Endomorphin-1 is highly conserved molecule so cross-reactivity with other species is expected. Cross-reactivity with other opioid peptides is as follows: with Endomorphin-2 = 70%; Met-enkephalin <0.03%; with Leu-enkephalin 0.01%; with beta-endorphin<0.1%.
||If you wish to use this product in a species other than those specified here and want to determine the amino acid sequence homology between the immunogen and the corresponding protein in that species, simply copy the amino acid sequence for this immunogen and test it on the BLAST database that you can access through the link below. Please note that antibodies raised against synthetic peptides are quite often very specific for that peptide. What this means in practise is that a single amino acid difference may be enough to restrict the specificity to a particular molecule.
The BLAST database can also be used to compare any amino acid sequence between species and between proteins. The full amino acid sequence of the target protein can be found by following the link in the Accession field. You can then search any amino acid sequence in the target protein using the BLAST database. When selecting a sequence to search, please choose carefully, as the sequence you choose may be a precursor rather than the mature protein for example.
||Lyophilised with BSA
||Reconstitute in 0.05 ml of PBS (pH 7.4) to achieve an antibody concentration of 1 mg/ml. Centrifuge to remove any insoluble material.
||At least 12 months after purchase at 2 - 4°C (lyophilized formulations).
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
||12 months after purchase
