Precision

Linearity

To assess the linearity of the assay, samples were spiked with high concentrations of rat LPS in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:1	Average %	95
	Range %	90-100
1:2	Average %	102
	Range %	96-107
1:4	Average %	98
	Range %	90-106
1:8	Average %	88
	Range %	82-104

Recovery

The recovery of rat LPS spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	93	84-100
EDTA plasma (n=4)	104	100-108

Typical Data

These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.

Materials provided

A micro ELISA plate ---The 96-well plate has been pre-coated with an anti-Rat LPS antibody.
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 LPS 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 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 incubating.

■ Q&A

I am interested in your kit Rat Lipopolysaccharides, LPS ELISA Kit (CSB-E14247r) (24 strip-well).
Taking into consideration the number of standards, how many samples can you analyse? Do you need to do this in duplicate?

Thanks for your inquiry.
CSB-E14247r
For this target, dilution is not needed if you test serum and plasma samples. We validated normal serum before and the test value is ND--0.25ng/ml. If you test samples of other modes, you can refer to the research situation of this mode and judge if pretest is needed or not. Take 24T as an example, if you run single well for the standard and the sample, you can test 16 samples. You can also run duplicated wells to reduce errors during the assay.
Pls let me know if you have any further questions. Thank you.

Intra-assay Precision (Precision within an assay): CV%<8%

Three samples of known concentration were tested twenty times on one plate to assess.

Inter-assay Precision (Precision between assays): CV%<10%

Three samples of known concentration were tested in twenty assays to assess.
