PGFM Assay a Hero in Predicting Panda’s Time of Birth
National Zoo Gains a Baby Panda
PGFM Assay a Hero in Predicting Time of Birth
The overjoyed zoo staff reported their resident Giant Panda, Mei Xiang, gave birth on August 21st, 2020, and you can watch both Mei Xiang and her new cub in real time on their Panda Cam! This is Mei Xiang’s fourth cub, and at 22 years old, she is the oldest panda in the U.S. to successfully give birth1. The zookeepers are “genuinely thrilled” about the birth not only because of the age of the mother, but because pandas are notoriously bad breeders, imperiling their species’ survival both in the wild and in captivity.
Many breeding programs, like the Smithsonian’s, use assay kits to measure reproductive hormones like estrogens and progesterone to determine ovulation. PGFM, a prostaglandin metabolite, is a useful, non-invasive pregnancy marker in both urine and fecal samples for predicting parturition or the timing of birth. Arbor Assays uses a highly specific antibody to measure PGFM, and the assay has been used in humans, pandas, buffaloes, cattle, cats, dogs, and mice. In the case of Mei Xiang, our PGFM ELISA Kit made one National Zoo staff member “a hero”!
