  • Product overview

    Catalase Activity Assay Kit (Colorimetric/Fluorometric) (ab83464) is a highly sensitive, simple and direct assay for measuring catalase activity in a variety of biological samples such as cell and tissue lysates or biological fluids.


    In the catalase activity assay protocol, the catalase present in the sample reacts with hydrogen peroxide (H2O2) to produce water and oxygen. The unconverted H2O2 reacts with probe to produce a product that can be measured colorimetrically at OD 570 nm or fluorometrically at Ex/Em = 535/587 nm. Therefore, the catalase activity present in the sample is reversely proportional to the signal obtained. The kit can detect as little as 1 µU of catalase activity.


    Catalase activity assay protocol summary:
    - add samples and standards to wells
    - add stop solution into sample control wells and incubate at 25ºC for 5 min
    - add H2O2 solution into wells and incubate for 30 min at 25ºC
    - add stop solution
    - add developer mix and incubate for 10 min at 25ºC
    - analyze with microplate reader

Measurement of the Catalase activity suggests a higher secretion level in a Gram positive mutant

Excellent Excellent 5/5 (Ease of Use)

abreview image
The highly sensitive and direct measurement of catalase activity in bacterial supernatants was performed by using the Catalase Activity Assay Kit (ab83464) from Abcam. Bacterial cells were grown in defined medium and harvested at late exponential phase by centrifugation at 15,000 x g for 20 min. The obtained supernatant was sterile filtrated with a 0.22 µm filter and was used for the assay. Standard preparation and assay procedure were done according to manufacturer‘s instruction for colorimetric assays. There were significant differences in the activity of catalase between bacterial mutant 1 and the wildtype. This suggests a higher catalase secretion in mutant 1. Compared to this observation, there are no differences by measuring the Superoxide dismutase activitiy (see see Superoxide dismutase acitivity assay from Abcam [ab65354])

Sample preparation – Microalgae.
1. Harvest the amount of microalgae necessary for each assay (initial recommendation = 15 mg).
2. Resuspend microalgae in 500 μL of cold Assay Buffer.
3. Sonicate the sample for 30 seconds on ice. Repeat three times.
4. Centrifuge 10 minutes at 4ºC at 10,000g using a cold microcentrifuge to remove any insoluble material.
5. Collect supernatant and transfer to a clean tube.
6. Keep on ice.

- It is recommended to perform several dilution of your sample to ensure the reading are within the standard value range. In this case the dilution factor was 1:100.

Question

ab83464

The HRP needs to be reconstituted to 200 ul in the catalase assay buffer. Is this enough for the assay?

Also, the concentration of HR@P added to wells via the CR solution is 1.5X higher than the top dose used for the standard curve. Therefore, it cannot be assumed that the fluorescence of the High Control (HC) wells is an accurate value to calculate the activity from. The solution would be to reduce the conc of H2O2 in the CR to fall within the top end of the standard curve

Asked on Feb 24 2017

Answer

Regarding the HRP  The amount of HRP once reconstituted in 200 ul is enough for 1 plate + 1 extra reaction (2 ul per reaction). This should therefore be enough for a 1 plate assay.   The 1 extra reaction amount means that if for example you want to split your experiments into 2X  separate assays using half a plate, you will need to be careful how much you use for the first assay and perhaps prepare master mix for half plate plus half a reaction.

The assay is measuring the amount of H2O2 left behind as it is used up by the catalase. The higher the catalase activity, the less H2O2 will be left at the end of the assay when it is measured.  The reason to add extra H2O2 is to ensure that the readings of the High Control (HC) and sample is within the standard curve.   For example, on the example shown on the datasheet, the sample data starts with OD 1.5 (HC) while the sample OD is 0.25. the difference in OD values is therefore almost near the upper end of the standard curve. It is to help ensure the sample values remain in the range of the assay if they contain a lot of catalase.

Question

This is regarding the Catalase Assay Kit (ab83464). In the Instructions for Use under 4. Assay Protocol (page 6), step B calls to prepare sample High Control (HC) with the same amount of sample in separate wells…What is a High Control? Is this the Positive Control using 5 µL? The wording “High Control” is very confusing.

Read More

Abcam community

Verified customer

Asked on Aug 01 2013

Answer


The High Control (HC) is a well that has the same volume of sample (2-78 uL) loaded as your sample wells. If you load wells with different volumes of sample, you will need to also load multiple HC wells with the same volume of sample. Prior to adding hydryogen peroxide to all of the wells, 10 uL of stop solution is added to each HC well and incubated for 5 minutes at 25 degrees Celsius to completely inhibit the catalase activity (step C). The HC well OD reading is used to calculate the signal changes by catalase in your samples as outlined in the Data Analysis section (page 9), serving as a baseline OD reading.

This is essentially a similar principle to subtracting a background OD reading (negative control), but since there is an inverse relationship between the OD reading and catalase activity with this assay, it is referred to as a High Control rather than a negative control.

Hola.

En la parte donde se encuentran las instrucciones de como realizar el ensayo, en la sección uno inciso b. Aparece una inidcación que dice lo sigueinte en idioma ingles (prepare sample High Control (HC) with the same amount of sample in separate wells then bring total volumen to 78 ul with Assay buffer).
Mi pregunta es a que se refiere con el High Control (HC), que es, como lo preparo.
Favor de aclararme la duda y en su caso indicarme como preparar el HC.

Asked on Apr 17 2013

Answer

Gracias por contactarnos.

En el kit tiene lugar la reacción de H2O2 para producir H2O y oxigeno catalizado por la enzima catalasa. El H2O2 que queda sin reaccionar reacciona con OxiRed™ generando un producto que presenta absorbancia medida a 570nm.

En el pocillo del High Control la reacción de conversión de H2O2 en agua y oxigeno se detiene antes de que tenga lugar, por eso se añade la Stop Solution. De esta forma, se puede saber la cantidad de H2O2 que había inicialmente en las muestras, sin que haya sido catalizada por la catalasa.

Al final, la absorbancia debida a la actividad de la catalasa vendrá dada por la siguiente ecuación: Abs (A)= Abs (HC) – Abs (simple).

La forma de preparar el HC es la misma que en las muestras: se añade la muestra primero (o el control positivo) y se ajusta el volumen hasta 78ul con Assay Buffer. Después se añaden 10ul de Stop Solution solo a los pocillos del HC, para inhibir la actividad de la enzima.

Espero haber aclarado la pregunta. En caso contrario no dudes en volverme a contactar.

Question

Good afternoon,

I'm interested in your kit ab83464 catalase assay kit. I've some questions about it: I've got a plate reader in my lab and I checked all the filters it has. Unfortunately, it has not 570nm filter for the colorimetric analysis, and 535/587 for the fluorometric, neither. I was just wondering if 545/590 could be nearly the same.
If I want to run the assay using mice urine, do you think it's better if I dilute the samples or make a test to work out which is the right concentration of urine I should use?

Kind regards

Answer

Thank you for contacting us.

I can confirm that the fluorimetric detection method can be used with the 545/590 filter. Please note that the expected results could be of less quality as reading results with a 535/587 filter would be.

I can confirm, that for unknown samples, we suggest testing several doses of the sample to ensure the readings are within the linear range.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

Dear ABCAM,

I used your kit ab83464 for the measurement of catalase activity on hippocampal rat samples. I strictly followed the instructions included, but unfortunately I found that the absorbance of high control samples was lower than (or equal to) that measured for the samples. Therefore, I could not calculate the value of catalase activity in my experimental samples. How could you explain this?

Thank you very much for the support

Thank you for your patience as I have investigated this issue further with the laboratory.


I can confirm that you performed the assay correctly the second time, only adding stop solution to the standards and HC ONCE.


It is not clear however, why the HC readings were lower than your samples. Were these freshly prepared samples? Do you have more samples and room on the plate to try again? If not, please provide an order number and I will send a replacement kit.


I look forward to your reply so that I may assist you further.
