人幾丁質酶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/分)。仔細收集上清,保存過程中如出現沉淀,應再次離心。
血漿樣本:應根據標本的要求選擇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/分)。仔細收集上清,保存過程中如有沉淀形成,應該再次
離心。
尿液樣本:用無菌管收集,離心20分鐘左右(2000-3000轉/分)。仔細收集上清,保存過程中如有沉淀形成,應再次離心。胸腹水、腦脊液參照實行。
細胞培養上清樣本:檢測分泌性的成份時,用無菌管收集。離心20分鐘左右(2000-3000 轉/分)。仔細收集上清。檢測細胞內的成份時,用PBS(PH7.2-7.4)稀釋細胞懸液,細胞
濃度達到100萬/ml 左右。通過反復凍融,以使細胞破壞并放出細胞內成份。離心20分
鐘左右(2000-3000 轉/分)。仔細收集上清。保存過程中如有沉淀形成,應再次離心。
組織標本:切割標本后,稱取重量。加入一定量的 PBS,PH7.4。用液氮迅速冷凍保存備
用。標本融化后仍然保持2-8℃的溫度。加入一定量的 PBS(PH7.4),用手工或勻漿器
將標本勻漿充分。離心20分鐘左右(2000-3000轉/分)。仔細收集上清。分裝后一份待
檢測,其余冷凍備用。
人幾丁質酶1(CHIT1)ELISA試劑盒標本采集后盡早進行提取,提取按相關文獻進行,提取后應盡快進行實驗。若不能馬上
進行試驗,可將標本放于-20℃保存,但應避免反復凍融,不能檢測含 NaN3 的樣品,因 NaN3 抑制辣根過氧化物酶的(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.
