Human 2,3-DPG ELISA Kit — FAQ for Hematology, Exercise Physiology, and Oxygen Transport Research

Human 2,3-DPG ELISA Kit: Your Questions Answered

2,3-Disphosphoglycerate (2,3-DPG) , also known as 2,3-bisphosphoglycerate (2,3-BPG) , is an organic phosphate molecule found primarily in red blood cells (erythrocytes) . It is a key regulator of hemoglobin oxygen affinity: 2,3-DPG binds to the β-subunits of deoxygenated hemoglobin, stabilizing the T (tense) state and promoting oxygen release to tissues. This makes 2,3-DPG a critical factor in oxygen delivery, altitude adaptation, and hemoglobinopathies.

Abbkine's Human 2,3-Disphosphoglycerate (2,3-DPG) ELISA Kit (KTE60832) provides researchers with a reliable tool for quantifying this important metabolic regulator in human samples. Here are answers to the most common questions about this kit and 2,3-DPG detection.

What is the detection principle of this 2,3-DPG ELISA kit?

This kit employs a competitive or sandwich ELISA format to quantitate 2,3-DPG in samples. An antibody specific for 2,3-DPG is pre-coated onto a microplate. When you add standards and samples, any 2,3-DPG present competes with or binds to the immobilized antibody. After removing any unbound substances, a detection antibody is added. Following washing, a substrate solution is added and color develops in proportion to the amount of 2,3-DPG bound. The color development is stopped and the intensity is measured — providing a quantitative, colorimetric readout.

What sample types can I use?

The kit is validated for serum, plasma, and other biological fluids. This makes it suitable for hematology research, exercise physiology studies, and clinical research applications.

What is the sensitivity and detection range?

Abbkine's ELISA kits are engineered for high sensitivity and excellent specificity. For specific sensitivity information tailored to your expected concentration range, contact Abbkine's technical support team.

Does this kit cross-react with other phosphate metabolites (2,3-BPG, 3-PG, etc.)?

No significant cross-reactivity or interference between human 2,3-DPG and analogues has been observed. This specificity ensures you're measuring 2,3-DPG specifically — without interference from related phosphate metabolites.

How should I store and handle the kit?

• Unopened kit: Store at 2–8°C
• Opened kit: Follow protocol-specific storage instructions
• Shipping: Gel pack with blue ice maintains temperature during transit

Critical handling tips:

• Allow all reagents to warm to room temperature for at least 30 minutes before opening
• Pre-rinse pipette tips with reagent; use fresh tips for each sample, standard, and reagent
• Mix thoroughly — use a low-frequency oscillator or gentle hand shaking every 10 minutes
• Run samples and standards in duplicate or triplicate
• Keep unused wells desiccated at 4°C in the provided sealed bag

What applications is this kit suitable for?

This kit is designed for research use only — not for human or clinical diagnosis. Applications include:

• Hematology and erythrocyte metabolism research
• Exercise physiology (oxygen delivery, altitude adaptation)
• Hemoglobinopathy research (sickle cell disease, thalassemia)
• Pulmonary and cardiovascular research
• Anemia and blood disorder studies
• Altitude medicine and hypoxia research
• Drug development (modulators of oxygen affinity)

Why measure 2,3-DPG?

2,3-DPG is a critical regulator of oxygen delivery:

• It decreases hemoglobin's oxygen affinity, promoting O₂ release to tissues
• 2,3-DPG levels increase in response to hypoxia (altitude, anemia, COPD)
• 2,3-DPG levels decrease in banked blood — affecting transfusion efficacy
• 2,3-DPG is a biomarker of oxygen transport efficiency in clinical and sports medicine

What's included in the kit?

A complete, ready-to-use kit.
