    Glucose Assay Kit (ab65333) measures glucose in various biological samples (e.g., serum, plasma, body fluid, food, growth medium, etc.).

    Glucose Enzyme Mix specifically oxidizes glucose to generate a product which reacts with a dye to generate color (λ = 570 nm) and fluorescence (Ex/Em = 535/587 nm). The generated color and fluorescence is proportionally to the glucose amount.

    The method is rapid, simple, sensitive, and suitable for high throughput. The assay is also suitable for monitoring glucose level during fermentation and glucose feeding in protein expression processes. The kit detects 1-10000 µM glucose samples.

    If you have reducing substances in your samples, we recommend using Glucose Detection Kit II (ab102517).

  • Shao et al investigated the functional outcome of long- term curcumin supplementation on glucose homeostasis. Glucose metabolism was determined in animals with low fat diet (LFD), high fat diet (HFD) and HFD with curcumin feeding  using ab65333. Intraperitoneal insulin tolerance tests(IPITT) were conducted at the end of the 26 weeks. It was concluded curcumin improves insulin sensitivity and disposal of glucose.

  • Glucose measured in cell lysates showing quantity (nmol) per million cells.

    Samples with the concentration of 2x107 cells/mL were used. Samples were diluted 1.5-13.5 fold and measured colorimetrically.

  • Glucose measured in human biological fluids showing quantity (µmol) per mL of tested sample. Samples were diluted 13.5 fold and measured colorimetrically.

The signal contributed by the phenol red in 1ul samples will be insignificant compared to the signal generated by the glucose in your samples. You should include a control consisting of 1ul of culture medium and subtract the absorbance or fluorome...

Thank you for contacting us. Yes, peroxide is known to interfere with this Glucose Assay Kit. I hope this helps, please let me know if you need any additional information.

This kit is only specific for D-glucose.

I have been in contact with the lab and unfortunately, we have not tested whether the addition of acids such as H2SO4 or PFA will interfere with the assay.

They have suggested that in this situation, perhaps it is best if you deproteinise you...

We have not tested glucose in purified polysaccharide samples. The first step of the reaction is specific for glucose, so we expect this to work. It's possible that there will be some background, but this can be corrected for by subtracting the backgro...

The main difference between these two glucose assays is that in ab65333 the probe reacts with hydrogen peroxide and gets oxidized to produce colored compound detectable at 570nm or at Ex/Em 535/587nm. In ab102517, the probe reacts with NADH (produced d...

I suggest exchanging the medium before collecting samples. That is, culture the cells in medium with a glucose/energy source and then exchange the medium with glucose-free medium such as Krebs-Ringer-Phosphate-HEPES (KRPH) buffer for example, and then ...

Thank you for your enquiry.

Answer 1: Yes, the minimal serum volume for this assay is 0.5 µl. The lower detection limit of this assay is 1 µM. That does not mean that you have to start with a particular conc of the sample. Mo...

This kit would be used to measure glucose in the cell culture supernatant. The number of cells in culture would have an effect on the glucose consumption, but the amount of time the cells are cultured and the specific cell line you are testing for will...
