Hepatic ASGP receptor image of 99mTc-NGA in normal rabbit[J]. Nuclear techniques, 1999, (11): 663-667.
新半乳糖人血清白蛋白(NGA)是肝细胞表面去唾液酸糖蛋白受体(ASGPR)的特异性配基。根据受体与配基结合的原理,报道了以99mTc标记的NGA与人血清白蛋白(HSA)在正常兔中显像行为的对比。结果表明99mTc-HSA呈现血池显像剂的行为,而99mTc-NGA则呈现肝脏受体显像剂的行为,并且若兔事先用100倍量未标记的NGA将肝脏受体饱和后,再用99mTc-NGA显像则呈现与99mTc-HSA相似的显像结果。以异硫氰酸荧光素标记的NGA(FITC-NGA)进行流式细胞分析(FCM)也表明,ASGPR具有明显可饱和性。由此进一步表明99mTc-NGA是ASGP受体显像,而非胶体显像;且具有饱和性.
Galactosylneoglycoalbumin (NGA) is aspecific ligand of asialoglycoproteinreceptor (ASGPR) in hepatocyte surface.In this paper
the imaging comparison of~99mTc-NGA and ~99mTc-HSA in normal rabbit imaging are reported. ~99mTo-HSAgenerated a blood pool image when injected into normal rabbit
while ~99mTo-NGAshowed a hepatic receptor image charateristics. If rabbit hepatic receptor had beensaturated with 100 times amounts of NGA
~99mTc-NGA would generate a blood poolimaging sunilar to ~99mTc-HSA. Flow cytometry (FCM) analysis with FITC-NGA alsoshowed that ASGPR could be obviously saturated. Therefore
~99mTc-NGA is ahepatic receptor image agent.
