Fully biologically active when compared to standard. The ED50 as determined by its ability to induce alkaline phosphatase production by murine MC3T3-E1 cells is 5-20μg/ml.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4, 1mM DTT, 0.05% Tween-80.
Endotoxin
Less than 0.1EU/μg of rMuDHH C23II as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background
Desert hedgehog protein also known as HHG-3 is a member of the hedgehog family which is encoded by the DHH gene. It is expressed in adult testes but not expressed in limb buds. DHH may be as a precursor that is auto-catalytically cleaved; the N-terminal portion is soluble and contains the signalling activity while the C-terminal portion is involved in precursor processing. Besides, DHH may have a function as a spermatocyte survival factor in the testes. Within the N-terminal peptide, murine DHH shares 97% and 100% amino acid (a.a.) sequence identity with human and rat DHH, respectively.
