4. 細(xì)胞培養(yǎng)上清：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(zhuǎn)/分）。仔細(xì)收集上清。檢測細(xì)胞內(nèi)的成份時，用PBS（PH7.2-7.4）稀釋細(xì)胞懸液，細(xì)胞濃度達(dá)到100萬/ml左右。通過反復(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)溆谩?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，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。若不能馬上進(jìn)行試驗，可將標(biāo)本放于-20℃保存，但應(yīng)避免反復(fù)凍融.
7. 不能檢測含NaN3的樣品，因NaN3抑制辣根過氧化物酶的（HRP）活性。

4. Cell culture supernatant: When detecting secreted components, collect with a sterile tube. Centrifugation for about 20 minutes (2000-3000 r / min). Carefully collect the supernatant. When testing intracellular components, dilute the cell suspension with PBS (pH 7.2-7.4) to a concentration of 1 million cells / ml. By repeated freezing and thawing, to destroy cells and release intracellular components. Centrifugation for about 20 minutes (2000-3000 r / min). Carefully collect the supernatant. If precipitation is formed during storage, it should be centrifuged again.
5. Tissue specimens: After cutting the specimen, weigh it. Add a certain amount of PBS, PH7.4. Rapid freezing with liquid nitrogen reserve. The specimen remained at 2-8 ° C after thawing. Add a certain amount of PBS (PH7.4), using a manual or homogenizer to homogenize the specimen. Centrifugation for about 20 minutes (2000-3000 r / min). Carefully collect the supernatant. After dispensing a to be tested, the remaining frozen spare.
6. Specimen collection as soon as possible after extraction, extraction according to the relevant literature, extraction should be carried out as soon as possible after the experiment. If not immediay test, specimens can be stored at -20 ℃, but should avoid repeated freezing and thawing.
7. Can not detect NaN3-containing samples because NaN3 inhibits horseradish peroxidase (HRP) activity.
