同时，以SQ-BSA为免疫原免疫Balb／c小鼠，经融合实验获得了三株分泌抗磺胺喹噁啉单克隆抗体的杂交瘤细胞株SQl_(12)A_(10)，SQ_(26)B_7，SQ_(28)H_7。

Secondly, there is a long-term increase in consumption of certain food preservatives or nitrites between sulfa agents of food color food, raw cottonseed oil, celery, etc., can also lead to decline in the quantity and quality of sperm.

其次，长期食用某些加有亚硝酸盐类食物防腐剂或间磺胺类食物有色剂的食品、生棉籽油、芹菜等，亦可导致精子数量和质量下降。

Inspections in the first half of 2007 showed that the average acceptance rate regarding pesticide residues in vegetables was 93.6 percent; those regarding clenbuterol hydrochloride contamination and sulfa drug residues in livestock products was 98.8 percent and 99.0 percent respectively; and that regarding chloromycetin in aquatic products was 99.6 percent, of nitrofuran 91.4 percent, and of pesticide residue over 95 percent in sample surveys done at production bases.

Methods According to the drinking water legislation in Europe threshold: 0.10mg/L NO2(superscript -, a rapid spot test method for nitrite in water was established by using an optimized composition of reagent mixture and a binary positive/negative response, conducted as follows: a tablet of a mixture of solid reagents containing sulfanilamide, N-(1-naphthyl) ethylene diamine dihydrochloride and sodium chloride was put on a spot test plate of Teflon mould, then, a drop of 30% HCl and a drop of water sample were added on the reagent material.

根据欧洲饮水法规亚硝酸盐限值(0.10mg/L)，使用一种优化的试剂混合物和二元的阳性－阴性反应，建立一种水中亚硝酸盐快速点滴检验法。结果将1片含磺胺、N-（1-萘）乙二胺二盐酸盐和氯化钠的固体试剂混合物放在聚四氟乙烯模的点滴检验板上。加1滴30%盐酸和1滴水样于试剂片上。

Commercially important covalent amides include several used as solvents; others are the sulfa drugs and nylon.
