Human Taste Receptor Type 1 Member 1 (TAS1R1) ELISA Kit — FAQ for Sensory Biology and Nutrition Researchers

Human TAS1R1 ELISA Kit: Your Questions Answered

Taste receptor type 1 member 1 (TAS1R1) , also known as T1R1, is a G protein-coupled receptor that forms a heterodimer with TAS1R3 to function as the umami (savory) taste receptor. This receptor complex is activated by L-amino acids and is responsible for detecting the umami taste, one of the five basic taste modalities. TAS1R1 is primarily expressed in taste bud cells of the tongue but has also been found in extra-oral tissues including the gut, where it plays roles in nutrient sensing and metabolic regulation.

Abbkine's Human Taste receptor type 1 member 1 (TAS1R1) ELISA Kit (KTE60482) provides researchers with a reliable tool for quantifying this important taste receptor in human samples. Here are answers to the most common questions about this kit and TAS1R1 detection.

What is the detection principle of this TAS1R1 ELISA kit?

This kit employs a two-site sandwich ELISA to quantitate TAS1R1 in samples. An antibody specific for TAS1R1 has been pre-coated onto a microplate. When you add standards and samples, any TAS1R1 present binds to the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TAS1R1 is added. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added and color develops in proportion to the amount of TAS1R1 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, cell culture supernatants, and other biological fluids. This flexibility makes it suitable for various experimental systems, from taste bud cell cultures to clinical research samples.

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 taste receptors (TAS1R2, TAS1R3)?

No significant cross-reactivity or interference between human TAS1R1 and analogues has been observed. This specificity ensures you're measuring TAS1R1 specifically — without interference from other taste receptor family members.

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:

• Sensory biology and taste perception research
• Umami taste signaling studies
• Nutrition and nutrient sensing research
• Extra-oral taste receptor function (gut, metabolic regulation)
• Drug development (taste modulators, appetite regulation)

What's included in the kit?

A complete, ready-to-use kit.
