犬*（LYS）酶聯(lián)免疫分析（ELISA）試劑盒
Generic Name：canine lysozyme (LYS) ELISA Kit
本試劑盒僅供研究使用，用于測(cè)定犬血清，血漿及相關(guān)液體樣本中*（LYS）含量。
樣本處理方法：
1. 血清：室溫血液自然凝固10-20分鐘，離心20分鐘左右（2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清，保存過(guò)程中如出現(xiàn)沉淀，應(yīng)再次離心。
2. 血漿：應(yīng)根據(jù)標(biāo)本的要求選擇EDTA或檸檬酸鈉作為抗凝劑，混合10-20分鐘后，離心20分鐘左右（2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清，保存過(guò)程中如有沉淀形成，應(yīng)該再次離心。
3. 尿液：用無(wú)菌管收集，離心20分鐘左右（2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清，保存過(guò)程中如有沉淀形成，應(yīng)再次離心。胸腹水、腦脊液參照實(shí)行。
4. 細(xì)胞培養(yǎng)上清：檢測(cè)分泌性的成份時(shí)，用無(wú)菌管收集。離心20分鐘左右（2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清。檢測(cè)細(xì)胞內(nèi)的成份時(shí)，用PBS（PH7.2-7.4）稀釋細(xì)胞懸液，細(xì)胞濃度達(dá)到100萬(wàn)/ml左右。通過(guò)反復(fù)凍融，以使細(xì)胞破壞并放出細(xì)胞內(nèi)成份。離心20分鐘左右（2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清。保存過(guò)程中如有沉淀形成，應(yīng)再次離心。
5. 組織標(biāo)本：切割標(biāo)本后，稱取重量。加入一定量的PBS，PH7.4。用液氮迅速冷凍保存?zhèn)溆?。?biāo)本融化后仍然保持2-8℃的溫度。加入一定量的PBS（PH7.4），用手工或勻漿器將標(biāo)本勻漿充分。離心20分鐘左右（2000-3000轉(zhuǎn)/分）。仔細(xì)收集上清。分裝后一份待檢測(cè)，其余冷凍備用。
6. 標(biāo)本采集后盡早進(jìn)行提取，提取按相關(guān)文獻(xiàn)進(jìn)行，提取后應(yīng)盡快進(jìn)行實(shí)驗(yàn)。若不能馬上進(jìn)行試驗(yàn)，可將標(biāo)本放于-20℃保存，但應(yīng)避免反復(fù)凍融.
7. 不能檢測(cè)含NaN3的樣品，因NaN3抑制辣根過(guò)氧化物酶的（HRP）活性。
試劑盒保存：2-8℃
有效期：6個(gè)月
Purpose
This kit allows for the determination of LYS concentrations in canine serum, blood plasma, and other biological fluids.
Specimen requirements
- serum- coagulation at room temperature 10-20 mins，centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
- plasma-use suited EDTA or citrate plasma as an anticoagulant,mix 10-20 mins ,centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
- Urine-collect sue a sterile container, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again. The Operation of Hydrothorax and cerebrospinal fluid Reference to it.
- cell culture supernatant-detect secretory components, collect sue a sterile container, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant,detect the composition of cells, Dilut cell suspension with PBS（PH7.2-7.4）, Cell concentration reached 1 million / ml, repeated freeze-thaw cycles, damage cells and release of intracellular components, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant, If precipitation appeared, Centrifugal again.
- Tissue samples- After cutting samples, check the weight,add PBS（PH7.2-7.4）, Rapidly frozen with liquid nitrogen, maintain samples at 2-8℃ after melting,add PBS（PH7.4）, Homogenized by hand or Grinders, centrifugation 20-min at the speed of 2000-3000 r.p.m. remove supernatant.
- extract as soon as possible after Specimen collection,and according to the relevant literature, and should be experiment as soon as possible after the extraction. If it can’t, specimen can be kept in -20 ℃ to preserve, Avoid repeated freeze-thaw cycles.
- Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.
