Recombinant Fruit fly Accessory gland-specific peptide 70A(SP)

P05623

Drosophila melanogaster (Fruit fly)

20-55aa

Yeast

4.3 kDa

Male seminal protein which triggers short- and long-term post-mating behavioral responses (PMR) in female Drosophila (PubMed:3135120, PubMed:19249273, PubMed:20308537, PubMed:19793753, PubMed:15694303, PubMed:24089336). Binds initially to sperm where it is later cleaved to release an active peptide within the female reproductive tract. Signals via the sex peptide receptor (SPR) in female flies; may also act via other receptors (PubMed:20458515, PubMed:20308537, PubMed:24089336). Moderates the activity of distinct neuronal circuitries in the female genital tract to promote specific PMRs including: enhanced ovulation, increased egg laying rate, increased feeding/foraging rate, induced antimicrobial peptide synthesis, reduced mating receptivity, reduced day-time sleep and reduced lifespan in multiple mated females (PubMed:3135120, PubMed:15694303, PubMed:19249273, PubMed:19793753, PubMed:24089336).

Greater than 90% as determined by SDS-PAGE.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20C/-80C. The shelf life of lyophilized form is 12 months at -20C/-80C.
