Albumin ELISA Kit

Catalog No. ABIN6973627

Product Details Albumin ELISA Kit

Target: Albumin (ALB)

Reactivity: Rabbit

Detection Method: Colorimetric

Method Type: Competition ELISA

Detection Range: 0.273 μg/mL - 70 μg/mL

Minimum Detection Limit: 0.273 μg/mL

Application: ELISA

Purpose: For the quantitative determination of rabbit albumin(Alb) concentrations in serum, plasma, urine.

Sample Type: Plasma, Serum, Urine

Analytical Method: Quantitative

Specificity: This assay has high sensitivity and excellent specificity for detection of rabbit albumin. No significant cross-reactivity or interference between rabbit albumin and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between rabbit albumin and all the analogues, therefore, cross reaction may still exist.

Sensitivity: 0.117 μg/mL

Components:

• Assay plate
• Standard
• HRP-conjugate (100 x concentrate)
• Sample Diluent
• HRP-conjugate Diluent
• Wash Buffer (25 x concentrate)
• TMB Substrate
• Stop Solution
• Adhesive Strip

Application Details

Application Notes: Optimal working dilution should be determined by the investigator.

Sample Volume: 50 μL

Assay Time: 1 - 4.5 h

Plate: Pre-coated

Protocol:

1. Prepare reagents, samples and standards as instructed.
2. Set a Blank well without any solution.
3. Add 50 µL standard or sample to each well.
4. Add 50 µL HRP-conjugate (1x) to each well (Not to Blank well).
5. Incubate 1 hour at 37 °C
6. Aspirate and wash 5 times.
7. Add 90 μL of TMB Substrate to each well. Incubate for 20 minutes at 37 °C. Protect from light.
8. Add 50 µL Stop Solution to each well. Read at 450 nm within 5 minutes.

Reagent Preparation:

1. HRP-conjugate (1x) - Centrifuge the vial before opening. HRP-conjugate requires a 100-fold dilution. A suggested 100-fold dilution is 10 μL of HRP-conjugate + 990 μL of HRP-conjugate Diluent.
2. Wash Buffer(1x)- If crystals have formed in the concentrate, warm up to room temperature and mix gently until the crystals have completely dissolved. Dilute 20 mL of Wash Buffer Concentrate (25 x) into deionized or distilled water to prepare 500 mL of Wash Buffer (1 x).
3. Standard Centrifuge the standard vial at 6000-10000rpm for 30s before opening. Dilute the Standard(10x) with Sample Diluent. A suggested 10-fold dilution is 30 μL of Standard(10x) + 270 μL of Sample Diluent. This diluted Standard (S5) serves as the high standard (70 μg/mL). Do not substitute other diluents. Mix the standard to ensure complete dilution and allow the standard to sit for a minimum of 15 minutes with gentle agitation prior to making dilutions. Pipette 150 μL of Sample Diluent into each tube (S0-S4). Use the diluted Standard (S5) solution to produce a 4-fold dilution series (below). Mix each tube thoroughly before the next transfer. Sample Diluent serves as the zero standard (0 μg/mL).

Note:

• Kindly use graduated containers to prepare the reagent. Please don't prepare the reagent directly in the Diluent vials provided in the kit.
• Bring all reagents to room temperature (18-25 °C) before use for 30 min.
• Prepare fresh standard for each assay. Use within 4 hours and discard after use.
• Making serial dilution in the wells directly is not permitted.
• Distilled water is recommended to be used to make the preparation for reagents or samples. Contaminated water or container for reagent preparation will influence the detection result.

Sample Preparation:

• It is recommended to use fresh samples without long storage, otherwise protein degradation and denaturationmay occur in these samples, leading to false results. Samples should therefore be stored for a short periodat 2 - 8 °C or aliquoted at -20 °C (≤1 month) or -80 °C (≤ 3 months). Repeated freeze-thawcycles should be avoided. Prior to assay, the frozen samples should be slowly thawed and centrifuged toremove precipitates.
• If the sample type is not specified in the instructions, a preliminary test is necessary to determinecompatibility with the kit.
• If a lysis buffer is used to prepare tissue homogenates or cell culture supernatant, there is a possibilityof causing a deviation due to the introduced chemical substance.The recommended dilution factor is for reference only.
• Please estimate the concentration of the samples before performing the test. If the values are not in therange of the standard curve, the optimal sample dilution for the particular experiment has to be determined.Samples should then be diluted with PBS (pH =7.0-7.2).

Note:

Recommend to dilute the serum or plasma samples with Sample Diluent(1:5000) before test. The suggested 5000-fold dilution can be achieved by adding 2 μL sample to 98 μL of Sample Diluent. Complete the 5000-fold dilution by adding 3 μL of this solution to 297 μL of Sample Diluent. The recommended dilution factor is for reference only. The optimal dilution factor should be determined by users according to their particular experiments. 6

Assay Precision: Intra-assay Precision (Precision within an assay): CV%<8% Three samples of known concentration were tested twenty times on one plate to assess.
