產品詳情

  • 產品描述：

    The Human Fibrinogen-like protein 1 (FGL1) ELISA Kit quantifies FGL1 in human serum, plasma, or tissue homogenates. It is not intended for diagnostic use. This assay kit was designed and optimized for cardiovascular research use in humans. The kit has undergone rigorous quality control in multiple parameters, including sensitivity, specificity, precision, linearity, recovery, and inter-batch difference. Refer to the product instructions for more details.

    This assay employs the quantitative sandwich enzyme immunoassay technique, in which FGL1 in the samples or standards are sandwiched between pre-coated FGL1 antibody and Biotin-conjugated FGL1 antibody. HRP-avidin is then added into the wells. Following a wash to remove any unbound reagent, the TMB substrate solution is added to the wells and color develops in proportion to the amount of FGL1 bound in the initial step. The color development is stopped upon adding the stop solution, and the intensity of the color is measured at 450 nm via a microplate reader. The levels of FGL1 in the samples can be determined by referring to the O.D. (optical density) of the samples to the standard curve.

    FGL1, also known as FREP1 or hepassocin, is a novel hepatocyte belonging to the fibrinogen family. It plays an important role in hepatic steatosis, insulin resistance, liver regeneration, and liver protection. FGL1 is normally released by the liver in low levels but by cancer in high levels. FGL1 acts as a major ligand of LAG-3 (Lymphocyte-activation gene 3) that mediates T cell inhibition, so blockade of the FGL1-LAG-3 interaction enhances antitumor immunity.

  • 本試劑盒所含材料：
      • A micro ELISA plate --- The 96-well plate has been pre-coated with an anti-human FGL1 antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
      • Two vials lyophilized standard ---Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
      • One vial Biotin-labeled FGL1 antibody (100 x concentrate) (120 μl/bottle) ---Act as the detection antibody.
      • One vial HRP-avidin (100 x concentrate) (120 μl/bottle) ---Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
      • One vial Biotin-antibodyDiluent (15 ml/bottle) ---Dilute the Biotin-antibody.
      • One vial HRP-avidin Diluent (15 ml/bottle) ---Dilute the HRP-avidin solution.
      • One vial Sample Diluent (50 ml/bottle)---Dilute the sample to an appropriate concentration.
      • One vial Wash Buffer (25 x concentrate) (20 ml/bottle) ---Wash away unbound or free substances.
      • One vial TMB Substrate (10 ml/bottle) ---Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
      • One vial Stop Solution (10 ml/bottle) ---Stop the color reaction. The solution color immediately turns from blue to yellow.
      • Four Adhesive Strips (For 96 wells) --- Cover the microplate when incubation.
      • An instruction manual

產品評價： 我用CSB-EL008653HU檢測正常和疾病組血清，原始OD值為0.1-40，兩組結果具有顯著差異，用WB驗證與之結果一致，認為該結果可信。該試劑盒質量好，靈敏度高。

■ 常見問題解答
Q:

我們想使用你們的FGL1 Elisa Kit CSB-EL008653HU。不幸的是，我們的血漿樣本中混入了檸檬酸鈉。但是說明書上只提到EDTA或肝素，我是否可以用這個試劑盒檢測我們的樣本？

A:
原則上，如果試劑不影響蛋白質結構變化(包括蛋白質變性)，則可以使用該試劑。但過酸或過堿的試劑會影響蛋白質。 我們一般是直接制備血漿檢測，不使用其他試劑(如乙酸鈉)，所以無法判斷會影響檢測結果。如果您的樣品尚未準備好，建議按照試劑盒的說明操作。如果已經準備好了，請安排一次預實驗來檢查結果。
