【日本生研】注意事项,保存,保质期,规格和Vi抗原检测---Precautions,Storage,Shelf Life,Format,Vi Antigen Determination
注意事项
当H诊断血清含有叠氮化钠时不能用于相诱导
沙门氏菌的H血清在诱导期不含防腐剂,因此所有过程需要无菌操作。
Precautions
As the H-antisera contain sodium azide they cannot be used for phase induction
Salmonella H-Sera for Phase induction contain no preservative, thus all manipulations should be conducted aseptically
保存
不要冷藏,因为诊断血清在冷冻解冻后可能会产生沉淀物
将试剂存放在2-10ºC下直到标签上的失效日期
Storage
Do not Freeze as freezing of antisera may produce a precipitate after thawing
Store the reagent at 2-10ºC up to the expiration date on the label
保质期
生产后2年
如果出现沉淀,使用前先过滤或用离心机分离
Shelf Life
2 years after production
Filter or centrifuge before using if precipitate is seen
规格
2~5 ml小瓶装不等
Format
Varies from 2 or 5 ml vials
Vi抗原检测
荚膜型抗原可能会伪装成体细胞抗原反应
如果所有的多价O型诊断血清测试为阴性则能与Vi诊断血清相区分
当在Vi诊断血清里得到一个阳性反应
将细胞悬浊液在100ºC下加热1小时,然后重复测定多价O型和Vi型.
如果O多价目前是阳性,Vi是阴性,那么这将会被视为S分型
如果O多价仍为阴性,Vi为阳性,则组织液可能不是沙门菌属并建议复验试验隔离
Vi Antigen Determination
This is a capsular antigen that can mask reaction of the somatic antigen
If all the Polyvalent O antisera are negative test isolate with Vi antisera
When a positive is obtained with the Vi antisera
heat cell suspension at 100ºC for 1 hr and repeat with Poly O and Vi.
If Poly O is now positive and Vi is now negative this should be regarded as S. typhi
If Poly O remains negative and Vi Positive, the organism may not be Salmonella and retesting the test isolate is recommended
