  • Product overview

    Cholesterol Assay Kit ab65390 uses a simple method to quantify total cholesterol, free cholesterol, and cholesterol esters in mammalian samples. It also includes an easy method to separate HDL and LDL / VLDL cholesterol. 


    In the cholesterol assay protocol, cholesterol oxidase acts on free cholesterol to produce a chemical which reacts with a probe to generate color (570 nm) and fluorescence (Ex/Em = 538/587 nm). Cholesterol esterase is used to hydrolyze cholesteryl ester into free cholesterol.


    If cholesterol esterase is included in the assay, total cholesterol is measured. If it is not included, free cholesterol is measured. The amount of cholesterol ester can be calculated by subtracting free cholesterol from total cholesterol.


    Note: this kit is primarily designed for use with serum and plasma samples. It has been successfully used with liver samples (including in Chang et al. 2019, Yu et al. 2018, and Sadh et al. 2017); sample preparation in liver (and other tissue) samples may need optimization and modification by the user for successful use. 


    Cholesterol assay protocol summary:
    - use complete sample for cholesterol measurement; or to separate HDL and LDL/VLDL, mix sample with precipitation buffer, incubate for 10 min, centrifuge for 10 min at 2,000 g, keep HDL fraction supernatant, repeat centrifugation and resuspend LDL/VLDL fraction pellet
    - for assay, add samples and standards to wells
    - add total cholesterol reaction mix (with esterase) or free cholesterol reaction mix (without esterase) and incubate for 60 min at 37ºC
    - analyze with microplate reader

The assay can be performed on a 384-well plate, which allows to scale down the volume to 1:5 than stated in the manual. Moreover, the assay allows detection of cholesterol in limited amounts of cerebrospinal fluid from single mice.

Rikard Fristedt - Cholesterol Assay Kit - HDL and LDL/VLDL (ab65390)

 Good Average 3/5 (Ease of Use)
Abreviews
I have done with all measurements using those kits and everything worked well. Of course, we need to read and understand the flow and procedure carefully beforehand to avoid confusion and mistake.

Just a little confusion about information of the kit, which made me really thought that we can measure all 3 parameters (HDL, LDL, and total cholesterol) for 100 samples for one kit. Unfortunately, it is not. Since I have 100 samples to measure all those 3 parameters, I then have to order more kits.”
Please make this clear from the beginning!

Overall, I am satisfied with the kits.

Total cholesterol from murine plasma samples

 Average Average 3/5 (Ease of Use)
Abreviews

This kit offers the possibility of measuring total cholesterol or HDL and LDL/VLDL fractions separately, which is an advantage over having to purchase two different kits.
I used this kit to measure total cholesterol from murine plasma samples obtained by cardiac puncture and centrifugation (4 C, 20 min, 2000 g) diluted 1:10 with PBS. The kit was easy to use and precise when the results were compared with historical records.
However, when I tried the separation step for HDL and LDL/VLDL fractions, I had the feeling that the design of the kit is not perfect as it is very easy to disturb the pellet and get contamination of your HDL fraction.

I tried many different product to get HDL and LDL/VLDL better and more clear but failed then I bought Cholesterol Assay Kit - HDL and LDL/VLDL (ab65390)to HDL and LDL/VLDL in obese mice serum to detect the effects of obesity on HDL and LDL/VLDL, as recommended in their datasheets and I never had any problem with it. I think its great product to use. I think this is best product to detect HDL and LDL/VLDL during in vivo studies

Measuring Cholesterol in Zebrafish Livers

 Excellent Good 4/5 (Ease of Use)
Abreviews
abreview image
I used the HDL and LDL/VLDL Cholesterol Assay Kit (Fluorometric) in order to measure total and free cholesterol in zebrafish liver. Overall the assay was successful. I did have some samples outside of the standard curve range meaning I will need to dilute my samples next time I run the assay. I divided all of my standard and sample fluorescence values by a factor of 10,000 prior to developing my standard curve. Attached is an image of my standard curve. From my standard curve I calculated the concentration of cholesterol that I then applied to the cholesterol concentration equation provided in the protocol. Some example data from my control sample is shown below.


Total Cholesterol: 57.7 ug/uL
Total HDL: 60.9 ug/uL
Total LDL/VLDL: 8.14 ug/uL

Free Cholesterol: 53.7 ug/uL
Free HDL :57.3 ug/uL
Free LDL/VLDL: 6.57 ug/uL

Cholesterol Esters: 3.99 ug/uL

Comparison of mouse liver extraction methods

 Good Excellent 5/5 (Ease of Use)
Abreviews
abreview image
I tried 2 extraction methods for mouse liver samples (from ApoE KO mice fed a high fat diet) that had been snap frozen and stored in -80 freezer.

I followed the Abcam sample preparation for tissue lysates and I also tried a protocol that had been posted by a previous reviewer of the product. See details below (copy pasted from previous reviewer):

For the separation of HDL and LDL/VLDL
1. Use 0.5% NP-40 in water to homogenize the tissue and then combine with the 2X precipitations buffer.
2. Mix 100 µL of sample with 100 µL of 2X Precipitation Buffer (1:1) in microcentrifuge tubes.
3. Incubate 10 minutes at room temperature.
4. Centrifuge at 2,000 x g (5,000 rpm on a bench-top microcentrifuge) for 10 minutes.
5. Transfer the supernatant into new labeled tubes. This is the HDL fraction.
6. Precipitates contain the LDL/VLDL fraction. To measure the LDL/VLDL fraction, centrifuge the precipitate again at 2,000 x g (5,000 rpm on a bench-top microcentrifuge at RT) for 10 minutes and remove trace amount of HDL supernatant carefully. I tissue homogenate you cannot measure the LDL fraction, only HDL!!!! (In tissue culture it is possibale).
7. Resuspend the precipitate in 200 µL PBS. This is the LDL/VLDL fraction.

If the supernatant is cloudy, the sample should be re-centrifuged. If the sample remains cloudy, dilute the sample 1:1 with PBS and repeat the separation procedure from step 2.

To homogenise the tissue I used a precellys 24 homogeniser.

Overall the protocols were similar but I preferred the Abcam one as all the reagents required are supplied within the kit. The alternative method requires NP-40 which is not supplied which would be expected.

From the image uploaded you can see that the 2 methods (Method 1 - Abcam Method 2 - user) produced very similar absorbance values (colorimetic method was used). The samples were diluted 5x to ensure they were within the standard curve.

Having compared the 2 methods I will proceed with using the Abcam method.

Overall this is a straightforward easy to use kit.

HDL and total cholesterol on liver tissue homogenates

 Good Good 4/5 (Ease of Use)

TISSUE PREPARATION
For total cholesterol
1. Homogenize 10 mg tissue in 200 μl of chloroform:Isopropanol:NP-40 (7:11:0.1) using a micro-homogenizer.
2. Spin the extract 10 minutes at 15,000 x g at RT in a centrifuge.
3. Transfer all of the liquid (organic phase) avoiding the pellet, to a new tube. Air dry the sup at 50°C to remove chloroform for 7min (in a hood).
4. Dissolve dried sup with Cholesterol Assay Buffer (1:1) by vortexing until homogeneous (it is OK if the solution becomes cloudy).

Note: The extraction procedure can be scaled up if larger amounts of sample are desired.

For the separation of HDL and LDL/VLDL
1. Use 0.5% NP-40 in water to homogenize the tissue and then combine with the 2X precipitations buffer.
2. Mix 100 µL of sample with 100 µL of 2X Precipitation Buffer (1:1) in microcentrifuge tubes.
3. Incubate 10 minutes at room temperature.
4. Centrifuge at 2,000 x g (5,000 rpm on a bench-top microcentrifuge) for 10 minutes.
5. Transfer the supernatant into new labeled tubes. This is the HDL fraction.
6. Precipitates contain the LDL/VLDL fraction. To measure the LDL/VLDL fraction, centrifuge the precipitate again at 2,000 x g (5,000 rpm on a bench-top microcentrifuge at RT) for 10 minutes and remove trace amount of HDL supernatant carefully.

Question

Is it acceptable to use EDTA-plasma with this assay kit (as compared to plasma produced with heparin)?

Read More
Answer

EDTA is not ideal for measurement of HDL/LDL in samples. EDTA plasma has potential disadvantages that have discouraged its use. Inadequate mixing can result in microclots. Also, EDTA osmotically draws water from red cells, diluting the plasma constituents.
