Produktdetails ESM1 ELISA Kit

Untere Nachweisgrenze: 15.63 pg/mL

Verwendungszweck: The kit is a sandwich enzyme immunoassay technique for the in vitro quantitative measurement in various sample types.

Analytische Methode: Quantitative

Spezifität: This kit recognizes natural and recombinantHumanESM1. No significant cross-reactivity or interference between HumanESM1 and analogues was observed. Note: Limited by existing techniques, cross reaction may still exist, as it is impossible for us to complete the cross-reactivity detection between HumanESM1 and all the analogues.

Anwendungsinformationen

Kommentare:

Information on standard material:
The formulation of the standard is 0.01 M PBS. The standard contains additives (1 % BSA).

Information on reagents:
Reagents include 1 M SO₂. Azide, thimerosal, 2-mercaptoethanol (2-ME) or any other poisonous materials are not used.

Information on antibodies:
The provided antibodies and their host vary in different kits. All antibodies are affinity purified

The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero. It was determined by adding two standard deviations to the mean optical density value of twenty zero standard replicates and calculating the corresponding concentration.

Probenmenge: 100 µL

Plattentyp: Pre-coated

Protokoll:

1. Add 100 µL standard or sample to each well. Incubate for 90 min at 37 °C.
2. Remove the liquid. Add 100 µL Biotinylated Detection Antibody. Incubate for 1 hour at 37 °C.
3. Aspirate and wash 3 times.
4. Add 100 µL HRP Conjugate. Incubate for 30 min at 37 °C.
5. Aspirate and wash 5 times.
6. Add 90 µL Substrate Reagent. Incubate for 15 min at 37 °C.
7. Add 50 µL Stop Solution. Read at 450 nm immediately.
8. Calculation of results.

Aufbereitung der Reagenzien:

1. Equilibrate all reagents to room temperature (18-25 °C) before use. If the kit will not be used up in one assay, please only take out the necessary strips and reagents for present experiment, and store the remaining strips and reagents at required condition.
2. Standard Working Solution: Centrifuge the standard at 10,000x g for 1 min. Reconstitute with 1 mL of the Standard & Sample Diluent, allow to stand for 10 minutes, and gently invert several times until completely dissolved. Alternatively, vortex briefly at low speed, remove bubbles by low-speed centrifugation if necessary.This produces a 1000 pg/mL stock solution. Prepare serial dilutions according to experimental requirements. Recommended dilution gradient: 1000, 500, 250, 125, 62.5, 31.25, 15.63, 0 pg/mL Serial Dilution Procedure: Dispense 500 μL of Standard & Sample Diluent into 7 EP tubes, respectively. Transfer 500 μL of the stock solution into the first tube. Sequentially transfer 500 μL from the preceding tube into the next tube for subsequent dilutions. Designate the last tube as the blank, do not transfer any solution into it. Aliquot the stock and store at -20 ° C. Use within two weeks and avoid repeated freeze-thaw cycles. Serially diluted standards should be prepared immediately, prior to use.
3. Biotinylated Detection Ab working solution: Calculate the required volume (100 μL/well) plus a slight excess. Centrifuge the Concentrated Biotinylated Detection Antibody (100x) at 800 x g for 1 minute. Dilute to 1x with Biotinylated Detection Ab Diluent at a ratio of 1:99. Prepare the working solution immediately, prior to use.
4. HRP Conjugate Working Solution: Calculate the required volume (100 μL/well) plus a slight excess. Centrifuge the Concentrated HRP Conjugate (100x) at 800 x g for 1 minute. Centrifuge the Concentrated HRP Conjugate (100x) at 800 x g for 1 minute. Prepare the working solution immediately, prior to use.
5. Wash Buffer: Prepare the working Wash Buffer by diluting 30 mL of Concentrated Wash Buffer with 720 mL of deionized or distilled water yielding 750 mL. Note: if crystals have formed in the concentrate, warm it in a 40 °C water bath and mix it gently until the crystals have completely dissolved. For same day use only.

Beschränkungen: Nur für Forschungszwecke einsetzbar

Handhabung

Handhabung: All the reagents in the kit should be stored according to the labels on vials. Unused wells should be returned to the foil pouch with the desiccant pack and resealed along entire edge of zip-seal. Substrate Reagent shouldn't be kept at -20 °C (Check!). Exposure of reagents to strong light should be avoided in the process of incubation and storage. All the taps of reagents should be tightened to prevent evaporation and microbial contamination. If not to store reagents according to above suggestions, erroneous results may occur.

Lagerung: 4 °C/-20 °C

Informationen zur Lagerung: The unopened kit can be stored at 4℃ for 1 month. If the kit is not used within 1 month, store the items separately according to the conditions since the kit is received.
