Sample GSM237688 Query DataSets for GSM237688
Status Public on Dec 26, 2007
Title Mammary_biopsy_IMF4_pooled (SAGE)
Sample type SAGE
Anchor NlaIII
Tag Count 7486
Tag Length 10
Source name biopsy of mammary parenchyma, milked 4 times daily beginning at day 4 of lactation, sampled at approx. day 7 of lactation
Organism Bos taurus
Characteristics Pooled total RNA isolated from mammary biopsies of 4 multiparous Holstein cows milked twice daily from days 1-3 of lactation and then 4 times daily beginning at day 4 of lactation. Biopsies performed at approximately day 7 of lactation.
Biomaterial provider Anthony V. Capuco, Bovine Functional Genomics Laboratory
Treatment protocol Four multiparous Holstein dairy cattle were milked twice daily during the first 3 days of lactation then 4 times daily until day 21 of lactation. Mammary biopsies were performed at approximately day 7 of lactation for extraction of total RNA, RNA pooling and subsequent SAGE library synthesis.
Growth protocol Multiparous Holstein dairy cattle were evaluated during the first week of lactation.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using the RNeasy Midi Kit (Qiagen, Valenica, CA). To remove contaminating genomic DNA, on-column DNase digestion was performed using the RNase-free DNase Set (Qiagen) according to kit instructions. RNA quality was assessed using the BioAnalyzer 2100 (Agilent Technologies, Palo Alto, CA) and concentrations were determined using a NanoDrop ND-1000 spectrophotometer (NanoDrop Technologies, Rockland, DE).
Description This library was constructed to compare to a library constructed from pooled RNA samples obtained from mammary biopsies of dairy cows milked twice daily.
Data processing SAGE2000, Version 4.5 software (Invitrogen Corp., Carlsbad, CA) was used to compare libraries, using a normalization value of 12000.
