1518811-8	1992	Independent G418-resistant colonies from site-specific integration of the reporter gene all showed nearly identical levels of beta-galactosidase activity when the reporter construct integrated at a particular chromosomal position.	antibiotic G 418	12-16	galactosidase beta 1	Homo sapiens	126-144	
9171933-14	1997	In both cases there was strong evidence for transfer of reporter genes (neo and LacZ) into the myeloma clone: morphologically abnormal G418-resistant colonies demonstrated intense staining for beta-galactosidase, and cytospin preparations showed 100% plasma cells with monoclonal heavy and light chain restriction.	antibiotic G 418	135-139	galactosidase beta 1	Homo sapiens	193-211	
15932276-2	2005	The insertion of two copies of the human interferon beta SAR element at the 5" and 3" flanking regions of the beta-galactosidase reporter gene increased the frequency of beta-galactosidase positive colonies by up to 75% and enhanced beta-galactosidase expression by 15- to 20-fold after G418 selection or 30- to 40-fold at the initial stage of the MTX selection procedure.	antibiotic G 418	287-291	galactosidase beta 1	Homo sapiens	110-128
