Human Glucose Elisa Kit

The Human Blood Glucose ELISA Kit is a sensitive and specific assay designed for the quantitative detection of blood glucose levels in human serum, plasma, urine, culture media, and other biological fluids. This kit is ideal for research on glucose metabolism, diabetes, and related disorders.

Sample Preparation

1. Serum Preparation

1. Collect whole blood and allow it to clot at room temperature for 10–20 minutes.
2. Centrifuge at 2,000–3,000 rpm for 20 minutes to separate the serum.
3. Re-centrifuge if precipitates appear during storage.

2. Plasma Preparation

1. Collect whole blood into tubes containing anticoagulants (e.g., EDTA or citrate).
2. Incubate at room temperature for 10–20 minutes.
3. Centrifuge at 2,000–3,000 rpm for 20 minutes to obtain plasma.
4. Re-centrifuge if necessary.

3. Urine Samples

1. Collect urine in aseptic tubes.
2. Centrifuge at 2,000–3,000 rpm for 20 minutes and carefully collect the supernatant.
3. Re-centrifuge if precipitates form during storage.

4. Cell Samples

1. For cell secretions, collect culture supernatants in aseptic tubes and centrifuge at 2,000–3,000 rpm for 20 minutes.
2. For intracellular components:
   • Dilute cells in PBS (pH 7.2–7.4) at 1×10⁷/mL.
   • Disrupt cells via repeated freeze-thaw cycles.
   • Centrifuge at 2,000–3,000 rpm for 20 minutes and collect the supernatant.

5. Tissue Samples

1. Cut and weigh tissue samples, then freeze in liquid nitrogen and store at -80°C.
2. Homogenize samples in PBS (pH 7.4) at 4°C.
3. Centrifuge at 2,000–3,000 rpm for 20 minutes and collect the supernatant.

Important Notes

1. Perform ELISA assays as soon as possible after sample collection.
2. Store samples at -20°C if immediate testing is not feasible.
3. Avoid repeated freeze-thaw cycles to preserve sample integrity.
4. Do not use samples containing sodium azide (NaN₃) as it inhibits HRP activity.
