  • 产品描述：

    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.

  • 本试剂盒所含材料：
      • 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.

■ 常见问题解答
Q:

我们想使用你们的FGL1 Elisa Kit CSB-EL008653HU。不幸的是，我们的血浆样本中混入了柠檬酸钠。但是说明书上只提到EDTA或肝素，我是否可以用这个试剂盒检测我们的样本？

A:
原则上，如果试剂不影响蛋白质结构变化(包括蛋白质变性)，则可以使用该试剂。但过酸或过碱的试剂会影响蛋白质。 我们一般是直接制备血浆检测，不使用其他试剂(如乙酸钠)，所以无法判断会影响检测结果。如果您的样品尚未准备好，建议按照试剂盒的说明操作。如果已经准备好了，请安排一次预实验来检查结果。
