2543671-2	1989	Using the cross-linking reagents disuccinimidyl suberate and dithiobissuccinimidyl propionate, we show that 125I-Epo can be specifically conjugated in a complex of 224kDa using mouse fetal liver cells, bone marrow cells, and Friend virus-induced splenic erythroblasts as demonstrated by electrophoresis on sodium dodecyl sulfate-polyacrylamide gels under nonreducing conditions.	Sodium Dodecyl Sulfate	306-328	erythropoietin	Mus musculus	113-116	
2460423-7	1988	Studies on binding and cross-linking of 125I-erythropoietin showed that ELM-I-1 cells had erythropoietin receptors, and two major radiolabeled protein products with molecular weights of 120 kDa and 140 kDa were detected on sodium dodecyl sulfate/polyacrylamide gel electrophoresis under reducing conditions.	Sodium Dodecyl Sulfate	223-245	erythropoietin	Mus musculus	45-59	
2822405-5	1987	Covalent binding of 125I-erythropoietin to its receptors with a cross-linking reagent, disuccinimidyl suberate or glutaraldehyde, resulted in the formation of two major radiolabeled products that migrated as 120-kDa and 140-kDa species on sodium dodecyl sulfate/polyacrylamide electrophoresis gels under reducing conditions.	Sodium Dodecyl Sulfate	239-261	erythropoietin	Mus musculus	25-39	
16098677-4	2005	The recombinant erythropoietin derived from mouse milk showed a different migration and distribution after SDS-PAGE electrophoresis as well as a low in vivo hematopoietic activity.	Sodium Dodecyl Sulfate	107-110	erythropoietin	Mus musculus	16-30
