The luteinizing hormone surge is essential for fertility as it triggers ovulation in females and sperm release in males. We previously reported that secretoneurin-a, a neuropeptide derived from the processing of secretogranin-2a (Scg2a), stimulates luteinizing hormone release, suggesting a role

Evolution of highly invasive placentation in the stem lineage of eutherians and subsequent extension of pregnancy set eutherians apart from other mammals, that is, marsupials with short-lived placentas, and oviparous monotremes. Recent studies suggest that eutherian implantation evolved from marsupial

The process by which a zygote develops from a single cell into a multicellular organism is poorly understood. Advances are hindered by detection specificity and sensitivity limitations of single-cell protein tools and by challenges in integrating multimodal data. We introduce

"As transgenic mouse core laboratories know well, mouse models are a powerful means of determining the function of mammalian genes in the context of whole organisms—especially since over 95% of the mouse genome is similar to the human genome. However, you may not know that:1. Laboratory mouse strains are descended from ancestors in modern-day Pakistan.2. The first inbred strain of lab mouse was created in 1909. It was named DBA for its coat color: dilute brown non-agouti.3. There is a mutant mouse actually named“Bad Hair Day” (Bhrd). Someone get this little guy a stylist!4. Male mice, when treated with anticancer drugs, have been shown to pass on DNA instability to their offspring.5. The founder of Jackson Laboratories, C. C. Little, once had lunch with Walt Disney to request that an animated film be created linking Mickey Mouse and the laboratory mouse. The request was denied."

Hi, we would like to double-check a couple of things: the sample is from human urine (not recombinant). How many mg of protein are present? We ordered 2.5 mg, so 7500 IU. 1l unit =2.35×10−12 moles, or 6×10−8 gram; so 450 ugs correct? Thanks
