人幾丁質(zhì)酶1(CHIT1)ELISA試劑盒
Human Chitinase 1(CHIT1)elisa Kit
試劑盒保存：2-8℃
有效期：6 個(gè)月
樣本處理方法：
血清樣本：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。
血漿樣本：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。
尿液樣本：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。
細(xì)胞培養(yǎng)上清樣本：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。
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)?br />用。標(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。
人幾丁質(zhì)酶1(CHIT1)ELISA試劑盒標(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，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。
Specimen requirements：
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. Can’t detect the sample which contain NaN3, because NaN3 inhibits HRP active.
