產品詳情

  • 產品描述：
    大鼠脫氫表雄酮(DHEA)酶聯免疫試劑盒（CSB-E08227r）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的DHEA含量。DHEA即脫氫表雄酮，是人體內重要的激素前體。它由腎上腺皮質、性腺及大腦分泌，參與體內多種生理過程。研究機制上，其可調節(jié)神經、免疫等系統(tǒng)功能，還與代謝、衰老等密切相關，目前在代謝性疾病、抗衰老等領域有廣泛研究。試劑盒檢測范圍為0.05 ng/mL-10 ng/mL，該產品適用于動物模型中的內分泌研究，如代謝綜合征、多囊卵巢綜合征的機制探索，或用于評估藥物干預對腎上腺功能的影響。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

Q:

Please provide the following information regarding Rat Dehydroepiandrosterone, DHEA ELISA Kit (CSB-E08227r): What is the active ingredient of the stop solution and its concentration?
What is the type, concentration, and state (liquid/lyophilized) of the preservatives used?
What is the expression host of the standard?
which components have H202 and the concentration of H202 in them?Just to confirm this I am inquiring for 24 and 96 well of this kit. Please confirm if the information will be the same for both the 24T and 96T in regards to Rat Dehydroepiandrosterone, DHEA ELISA Kit (CSB-E08227r)?
**if the preservative/s are not liquid, what is the concentration of the component prior to reconstitution (while still lyophilized)?

A:
Thanks for your inquiry.
CSB-E08227r
Standard is purified DHEA.
Stop solution is 4N sulfuric acid.
Preservative is proclin 300(1:3000 dilution）.
Sorry we can not disclose which components have H202 and the concentration of H202 in them.
For 24T and 96T, the component information is the same. Only the volume of reagents is different.
Pls let me know if you have any further questions. Thank you.
Q:

Can you please clarify if the preservative is liquid or lyophilized?
If it's lyophilized, please let us know concentration too.

A:
Thanks for your further inquiry. It is liquid.
