Molecular cloning of mouse placental lactogen cDNA.
We have isolated a cDNA clone for the 23-kDa mouse placental lactogen II (mPL-II) from a phage lambda gt11 expression library containing cDNA synthesized from BALB/c placental RNA. Translation in vitro of placental mRNA selected by hybridization to the mPL-II cDNA clones yields a 26-kDa polypeptide that is the size of the expected precursor protein and that is immunoprecipitated with anti-mPL-I...
متن کاملMolecular cloning of a mouse submaxillary gland renin cDNA fragment.
The mRNA encoding mouse renin has been partially purified from total poly(A)-containing RNA of submaxillary glands of male Swiss mice. Corresponding cDNAs were cloned in the Pst I site of pBR322. Recombinants have been characterized by differential screening and hybrid-arrested translation. The DNA of clone pRn3-5 has been used to study the expression of renin mRNA in the submaxillary gland and...
متن کاملIsolation, purification, and characterization of mouse placental lactogen.
Mouse placental lactogen was purified 1840-fold from BALB/c placentae from days 14-18 of gestation with an overall yield of 29%. The purification procedure included alkaline homogenization and extraction, ammonium sulfate precipitation, hydrophobic interaction chromatography on Phenyl-Sepharose, ion-exchange chromatography on CM- and DEAE-cellulose, and gel exclusion chromatography on Sephadex ...
متن کاملCo-localization of placental lactogen-I, placental lactogen-II, and proliferin in the mouse placenta at midpregnancy.
This study was undertaken to determine whether mouse placental lactogen (mPL)-I, mPL-II, and proliferin (PLF) are expressed by the same population of placental giant cells at midpregnancy. Tissue sections from Day 9 of pregnancy were analyzed by double immunofluorescence staining. Sections were stained for PLF by use of a rhodamine-conjugated second antibody, and for mPL-I or mPL-II by use of a...
متن کاملPlacental-specific expression from the mouse placental lactogen II gene promoter.
The gene for mouse placental lactogen II (mPL-II) has been isolated and characterized. This gene contains five exons, with a transcription start site 59 nucleotides upstream of the translation initiation ATG. Introduction of a DNA construct containing 2.7 kilobases of sequence upstream of the mPL-II transcription initiation site directed the synthesis of a linked coding region for the simian vi...
