Recombinant Human Semenogelin-1/SEMG1 is produced with our mammalian expression system in human cells. The target protein is expressed with sequence (Gln24-Thr402) of Human SEMG1 fused with a polyhistidine tag at the C-terminus.

Lyophilized
Reconstitution
It is not recommended to reconstitute to a concentration less than 100 μg/mL. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Buffer
Lyophilized from a 0.2 μm filtered solution of 20 mM Hac-NaAc, 150 mM NaCl, pH 4.5.
Conseil sur la manipulation
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.

Stockage commentaire
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Semenogelin-1 (SEMG1) is the predominant protein in semen, it is a secretory protein involved in the formation of a gel matrix entrapping the accessory gland secretions and ejaculated spermatozoa. The prostate-specific antigen (PSA) protease processes SEMG1 into smaller peptides, each possibly having a separate function. In the proteolysis process, Alpha-inhibin-92 and alpha-inhibin-31 are produced, they inhibit the secretion of pituitary follicle-stimulating hormone. At the same time, it breaks down the gel matrix, allowing the spermatozoa to move more freely.
