在不同培养条件下,来自2日龄雏鸡骨髓的红系细胞在纤维蛋白凝块中的克隆生长已被用作贫血鸡血浆中发现的血红素、集落和爆发刺激活性的独立测定。通过凝胶过滤、等电聚焦、耐热变性、硫酸铵沉淀、DEAE-层析或HAP-层析分析血红素刺激活性的性质,表明血清转铁蛋白为血红素刺激因子。贫血鸡血浆中的血红素、集落和爆发刺激因子不能通过凝胶过滤或等电聚焦相互分离。从鸡蛋白色的卵转铁蛋白也表现出血红素,集落和爆发刺激活性的测定,即使在进一步纯化后,通过有限的胰蛋白酶消化,电泳,羟基磷灰石色谱法或分级ConA-琼脂糖色谱法。
Clonal growth of erythroid cells from bone marrow of 2-day-old chicks in fibrin clots under different culture conditions has been used as independent assays for heme-, colony- and burst-stimulating activities found in anemic chicken plasma. The properties of the heme-stimulating activity analyzed by gel filtration, isoelectrofocusing, resistance to heat denaturation, ammonium sulfate precipitation, DEAE-chromatography or HAP-chromatography, suggested serum transferrin as the heme-stimulating factor(s). Heme-, colony- and burst-stimulating factor(s) from anemic chicken plasma did not separate from each other by gel filtration or isoelectrofocusing. Ovotransferrin from egg white also showed heme-, colony- and burst-stimulating activities by the assay employed even after further purification by limited trypsin digestion, electrophoresis, hydroxylapatite chromatography or fractionation by ConA-Sepharose chromatography.
