group ii ( b2 ) and group iii ( b4 ) antibodies were used to select the corresponding mutants , mar b2.1 and mar b4.1 , which in addition to carrying the mar phenotype were temperature sensitive ( ts ) for processing of the major partially glycosylated precursor of gb , pgb ( mr = 107,000 ) , to mature gb ( mr = 126,000 ) and showed reduced levels of gb on the cell surface at high temperature ( 39 degrees c ) .
