PS-2人早老素2檢測試劑盒樣品準備:

1. Acidify the plasma/serum with an equal amount of buffer A. For example, if you are using 1ml of plasma/serum, add 1 ml of buffer A. Mix and centrifuge at 6,000 to 17,000 x g for 20 minutes at 4°C.

2. Equilibrate a SEP-COLUMN containing 200 mg of C18 (Catalog No.: RK-SEPCOL-1) by washing with buffer B (1 ml, once) followed by buffer A (3 ml, 3 times).NOTE: From steps 3-5, no pressure should be applied to the column.

3. Load the acidified plasma/serum solution onto the pre-treated (Step 2) C-18 SEP-COLUMN.

4. Slowly wash the column with buffer A (3 ml, twice) and discard the wash.

5. PS-2人早老素2檢測試劑盒Elute the peptide slowly with buffer B (3 ml, once) and collect eluant into a polystyrene tube.

6. Evaporate eluant to dryness in a centrifugal concentrator or by a suitable substitute method.

7(i). For EIA kits, Fluorescent EIA kits and Chemiluminescent EIA kits, keep the dried extract at -20°C and perform the assay as soon as possible. For normal subject extracted from 1 ml original plasma/serum, use 125 ul 1x assay buffer to reconstitute the dried extract. Aliquot 50 ul into two designated assay wells (25 ul is left over). the concentration factor in this case is 8. (1 ml / 125 ul = 8). The original plasma peptide level is 1/8 of the level of final extracted plasma.

PS-2人早老素2檢測試劑盒樣本要求:

在收集標本前都必須有一個完整的計劃，必須清楚要檢測的成份是否足夠穩(wěn)定。我們提倡新鮮標本盡早檢測，對收集后當天就進行檢測的標本，及時儲存在4℃?zhèn)溆茫�如有特殊原因需要周期收集標本，請造模取材后，將標本及時分裝后放在-20℃或-70℃條件下保存。因冰室與室溫存在一定溫差，蛋白極易降解，直接影響實驗質(zhì)量，所以避免反復(fù)凍融。代測放免標本的客戶取材前須向我司銷售人員索要說明書，具體操作注意事項請與我司技術(shù)人員溝通。
