Rat Atp2a3(Sarcoplasmic/endoplasmic reticulum calcium ATPase 3) ELISA Kit

Kit Components：

Specificity：

This assay has high sensitivity and excellent specificity for detection of Atp2a3  . No significant cross-reactivity or interference between Atp2a3  and analogues was observed.

Note: Limited by current skills and knowledge, it is difficult for us to complete the cross-reactivity detection between Atp2a3  and all the analogues, therefore, crossr eaction may still exist.

Recovery：

Matrices listed below were spiked with certain level of Atp2a3 and the recovery rates were calculated by comparing the measured value to the expected amount of  Atp2a3  in samples.

Linearity：

The linearity of the kit was assayed by testing samples spiked with appropriate concentration Atp2a3 and their serial dilutions. The results were demonstrated by percentage of calculated concentration to the expectation.

Precision： 

Intra-Assay: CV<8%

Inter-Assay: CV<10%

Stability：

The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 10% within the expiration date under appropriate storage condition.

Principle of the Assay：

Operation Procedure：

This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Capture  antibody was pre-coated onto 96- well plates. And the biotin conjugated antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and washed with wash buffer. HRP-Streptavidin was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that  changed into yellow after adding acidic stop solution. The density of yellow is proportional to the target amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of targetcan be calculated.

Precautions：

1.To inspect the validity of experiment operation and the appropriateness of sample dilution proportion, pilot experiment using standards and a small number of samples isrecommended.

2.After opening and before using, keep platedry.

Material Required but Not Supplied：

1.Microplate reader(wavelength:450nm)。

2.37°Cincubator。

3.Automated platewasher。

4.Precision single and multi-channelpipette and disposable tips。

5.Clean tubes and Eppendorftubes。

Washing：

Manual: Discard the solution in the plate without touching the side walls. Clap the plate on absorbent filter papers or other absorbent material. Fill each well completely with 350ul wash buffer and soak for1to 2minutes,then aspirate contents from theplate,andclaptheplateonabsorbentfilterpapersorotherabsorbentmaterial.

Automatic: Aspirate all wells, and then wash plate with 350ul wash buffer. After the final wash, invert plate, and clap the plate on absorbent filter papers or other absorbent material. It is recommended that the washer shall be set for soaking1 minute.(Note:settheheightoftheneedles;besurethefluidcanbesippedupcompletely)。
