Human Estradiol 17-beta-dehydrogenase 2 ELISA Test Kit Strong Sensitivity HSD17B2 ELISA Kit
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.
CV(%) = SD/mean x 100
This Sandwich ELISA Kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with human HSD17B2 antibody. HSD17B2 present in the sample is added and binds to antibodies coated on the wells. And then biotinylated human HSD17B2 Antibody is added and binds to HSD17B2 in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated HSD17B2 antibody. After incubation unbound Streptavidin-HRP is washed away during a washing step. Substrate solution is then added and color develops in proportion to the amount of human HSD17B2. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.
Standard Curve Range: 0.2ng/ml - 60ng/ml
Size: 96 wells
Storage: Store the reagents at 2-8°C. For over 6-month storage refer to the expiration date keep it at -20°C. Avoid repeated thaw cycles. If individual reagents are opened it is recommended that the kit be used within 1 month.
*This product is for research use only, not for use in diagnosis procedures. It’s highly recommend to read this instruction entirely before use.
All reagents should be brought to room temperature before use.
Standard Reconstitute the 120μl of the standard (64ng/ml) with 120μl of standard diluent to generate a 32ng/ml standard stock solution. Allow the standard to sit for 15 mins with gentle agitation prior to making dilutions. Prepare duplicate standard points by serially diluting the standard stock solution (32ng/ml) 1:2 with standard diluent to produce 16ng/ml, 8ng/ml, 4ng/ml and 2ng/ml solutions. Standard diluent serves as the zero standard(0 ng/ml). Any remaining solution should be frozen at -20°C and used within one month. Dilution of standard solutions suggested are as follows:
|32ng/ml||Standard No.5||120μl Original Standard + 120μl Standard Diluent|
|16ng/ml||Standard No.4||120μl Standard No.5 + 120μl Standard Diluent|
|8ng/ml||Standard No.3||120μl Standard No.4 + 120μl Standard Diluent|
|4ng/ml||Standard No.2||120μl Standard No.3 + 120μl Standard Diluent|
|2ng/ml||Standard No.1||120μl Standard No.2 + 120μl Standard Diluent|
|Standard Concentration||Standard No.5||Standard No.4||Standard No.3||Standard No.2||Standard No.1|
Wash Buffer Dilute 20ml of Wash Buffer Concentrate 25x into deionized or distilled water to yield 500 ml of 1x Wash Buffer. If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved.
1. Prepare all reagents, samples and standards.
2. Add sample and ELISA reagent into each well. Incubate for 1 hour at 37°C.
3. Wash the plate 5 times.
4. Add substrate solution A and B. Incubate for 10 minutes at 37°C.
5. Add stop solution and color develops.
6. Read the OD value within 10 minutes.
