A major cell-surface glycoprotein of the TA3-Ha ascites mammary adenocarcinoma diminished during transfer from ascites growth to cell growth in suspension culture. A sensitive, hemagglutination-inhibition assay that used a lectin from Vicia graminea seeds indicated approximately a 50% loss after
Previous studies have demonstrated that a unique glycoprotein can be cleaved by trypsin from the plasma membrane of the Ha, but not the St, subline of the TA(3) murine mammary adenocarcinoma. Using an automated quantitative method for measurement of trypsincleaved fragments (glycoprotein fraction I)
We described the in vivo conversion of the strain-specific ascites murine mammary adenocarcinoma subline TA3-St to a new ascites subline designated TA3-MM. This conversion occurred during passage in a syngeneic A/HeHa mouse infected with pneumonia-producing microorganisms. The mode number of
It has been shown by us that the human blood-group MN antigenic determinants are not the products of allelomorphic genes as believed so far, but that N is the precursor substance of M and that the allelomorph to the M gene is amorph. The determinant structure of the N antigen is branched and
