| Product type | ELISA |
| Quantity | 96 Tests (12x8 breakable strip wells) |

| Analytical Sensitivity | 3 pg/ml |
| Sample volume | 25 µl/well |
| Species | Mouse or Rat |
| Application | The Calbiotech Mouse/Rat Estradiol (E2) ELISA Kit is intended for the quantitative determination of Estradiol (E2) concentration in Mouse or Rat serum and plasma. |
| Principle | The Calbiotech Mouse/Rat E2 ELISA kit is based on the principle of competitive binding between E2 in the test specimen and E2 enzyme conjugate for a constant amount of anti-Estradiol polyclonal antibody. In the incubation, anti-E2 antibody coated wells are incubated with E2 standards, controls, samples, and E2 enzyme conjugate at room temperature for 120 minutes with. During the incubation, a fixed amount of HRP-labeled E2 competes with the endogenous E2 in the standard, sample, or quality control serum for a fixed number of binding sites of the specific E2 antibody. E2 peroxidase conjugate immunologically bound to the well progressively decreases as the concentration of E2 in the specimen increases. Unbound E2 peroxidase conjugate is then removed and the wells are washed. Next, a solution of TMB Reagent is added and incubated at room temperature for 15 minutes, resulting in the development of blue color. The color development is stopped with the addition of stop solution, and the absorbance is measured spectrophotometrically at 450 nm. A standard curve is obtained by plotting the concentration of the standard versus the absorbance. |

使用方法：
1、 血清：操作过程中避免任何细胞刺激。使用不含热原和内毒素的试管。收集血液后，1000×g离心10分钟将血红细胞迅速小心地分离。
2、 血浆：EDTA、柠檬酸盐、肝素血浆可用于检测。1000×g离心30分钟去除颗粒。
3、 细胞上清液：1000×g离心10分钟去除颗粒和聚合物。
4、 组织匀浆：将组织加入适量生理盐水捣碎。1000×g离心10分钟，取上清液。
5、 保存：如果样品不立即使用，应将其分成小部分-70℃保存，避免反复冷冻。尽可能的不要使用溶血或高血脂血。如果血清中大量颗粒，检测前先离心或过滤。不要在37℃或更高的温度加热解冻。应在室温下解冻并确保样品均匀地充分解冻。
