Rat placenta growth factor,PLGF ELISA kit
Product Details
| Description |
The Rat placenta growth factor(PLGF)ELISA Kit allows for the in vitro quantitative determination of PLGF concentrations in serum, plasma, or tissue homogenates. The detection mechanism of this kit is based on the Sandwich-ELISA technique. PLGFin the sample is bound to the anti-rat PLGFantibody immobilized on the microtiter plate and then sandwiched with a Biotin-labeled PLGFantibody. The solution color develops into blue after the ordinal addition of HRP-avidin and TMB. The color development is terminated after adding the stop solution, and the color turns from blue to yellow. The color intensity is positively correlated with PLGFcontent in the sample.
This kit exclusively recognizes rat PLGF. The kit has been quality controlled with high sensitivity, strong specificity, good linearity, precision less than 10%, recovery with 89%-98%, and high lot-to-lot consistency. Refer to the product manual for more information.
PLGF is a member of the VEGF (vascular endothelial growth factor) family and is mainly expressed in the placenta. It is a crucial molecule in angiogenesis and vasculogenesis, in particular during embryogenesis. Specifically, PLGF plays a role in trophoblast growth and differentiation. In human atherosclerotic lesions, PLGF expression is linked to plaque inflammation and neovascular growth. PLGF is also a potential biomarker for pre-eclampsia, a pregnancy complication characterized by hypertension and proteinuria in pregnancy.

| Linearity |
| To assess the linearity of the assay, samples were spiked with high concentrations of rat PLGF in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. |

| Materials provided |
- A micro ELISA plate --The 96-well plate has been pre-coated with an anti-rat PLGF 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 PLGF 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-antibody Diluent (15 ml/bottle) --Dilute the high concentration Biotin-antibody to an appropriate working solution.
- One vial HRP-avidin Diluent (15 ml/bottle) --Dilute the high concentration HRP-avidin solution to an appropriate solution.
