    Ruminant placentas synthesize pregnancy-associated glycoproteins (PAGs) during pregnancy, which serve as biomarkers of pregnancy. The present study was conducted to verify, whether PAGs are expressed in buffalo placenta by using lectin-based affinity chromatography and peptide mass finger printing (PMF). Fetal cotyledonary tissues were collected from gravid uteri procured from slaughtered house. Proteins were extracted and subjected to wheat germ agglutinin (WGA) lectin affinity chromatography to isolate the PAGs. The isolated glycoproteins were separated by one-dimensional SDS-PAGE. PMF results of the 75 kDa protein revealed presence of two PAGs (PAG-7 and -11). The PAG-7 consisted of about 170 mass signals, of which 16 were assigned to corresponding/translated cDNA sequences of buffalo PAG-7, leading to sequence coverage of 40%. PMF result of PAG-11 showed 170 mass signals, of which 15 were assigned to buffalo PAG-11, leading to sequence coverage of 34%. In conclusion, the glycoprotein isolated from placental extract corresponding to 75 kDa band on SDS PAGE gel was a mixture of PAG-7 and -11, which may help in development of suitable diagnostics for pregnancy in buffalo.

    Peptide Identification Using Tandem Mass Spectrometry

    Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
    This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...

    Western Blotting

    Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
    The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.
