title: GSM2628959: OLB_ZT04; Papio anubis; RNA-Seq
library_construction_protocol: Twelve male Papio anubis hamadryas (age 5-6 yrs, 7-11 kg) were maintained in a 12hr light-12 hr dark cycle. Animals were fed twice a day (at 9:00 and 15:00) with fruits and primate meal pellets, with access to water ad libitum. Timed biosamples were collected every 2 hrs from ZT0 to ZT22, one primate at each sample time. The Institute veterinary services administered animals a lethal dose of sodium pentobarbital, after which blood (centrifuged for plasma), urine and CSF samples collected. Animals were perfused through the left ventricle with 4 liters of ice cold (2°C) buffered, oxygenated Ame's solution. Collection of brain sections used standardized procedures for NHPs (Davenport et al., 2013). The brain and eyes were rapidly removed (less than 5 min) and kept at 4°C on ice. Tissue collections were made simultaneously in three stations. In Station 1, the brain was cut into serial sections using a specifically built baboon brain matrix. Sections were placed on individual ice cold plates, each section photographed and punches obtained from selected brain structures. Sections were packaged in individual sterilized plastic pouches (Nasco) then frozen in dry ice and stored at -80°C. At the same time (Station 2), samples were taken from the eyes (retina, RPE, vitreous, lens, cornea, iris, optic nerve), divided into aliquots and frozen in dry ice. During the night-time periods, the head and eyes were covered with opaque plastic prior to perfusion and dissections of the eye and retina were performed in the dark using infrared viewers. Station 3 collected various body tissues and organs. All tissues were distributed into individual aliquots with certain larger tissues stored in bulk samples (liver, muscle, etc.), frozen in dry ice, and then stored at -80°C. The whole procedure, from collection to storage lasted no more than 30-40 min. Libraries were prepped using Illumina’s TruSeq Stranded mRNA HT kit according to manufacturer’s instructions.  In brief, total RNA starting with 1ug was poly-A selected, fragmented by metal-ion hydrolysis and then converted to cDNA using SuperScript II.  The cDNA was then end-repaired, adenylated and ligated with Illumina sequencing adapters.  Finally, the libraries were enriched by PCR amplification.  Libraries were pooled and sequenced using an Illumina HiSeq 2500 with 50-bp single-read chemistry.
