  • Product overview

    Hydroxyproline Assay Kit (Colorimetric) ab222941 provides a quick and convenient method to quantify hydroxyproline in tissue lysates and biological fluids such as urine and serum.


    The classical hydroxyproline assay protocol is based on the oxidation of hydroxyproline to a pyrrole intermediate followed by reaction with Ehrlich’s reagent dissolved in concentrated perchloric acid. Perchloric acid is a hazardous material that is both toxic and highly reactive, requiring special handling and waste-disposal protocols.


    This hydroxyproline assay protocol employs a proprietary acidic developer solution to accurately measure hydroxyproline in hydrolysates without the use of hazardous perchlorates. It is a quick and convenient protocol where hydroxyproline gets oxidized to form a reaction intermediate, which further in reaction forms brightly-colored chromophore that can be easily detected at OD 560 nm.


    The assay can detect as low as 0.05 µg hydroxyproline/well.

  • Notes

    This product is a replacement for Hydroxyproline Assay Kit K555; this kit does not contain the hazardous Perchloric acid which is present in K555.

    The components in this product are exactly the same as in K555, except that the Perchloric acid/Isopropanol Solution component in K555 has been replaced with the Developer component.

    If you would prefer to continue to use a kit in the format of K555, then use this product and:

    1) a) purchase 70% Perchloric Acid (ab291263) and Isopropanol (ab291264), or b) separately purchase 70% Perchloric Acid and 99% Isopropanol through another supplier.

    For safety reasons, Perchloric Acid will not be shipped by Abcam in the same shipment as either Isopropanol or this product.

    2) In a fume cupboard, mix 1 ml of 70% Perchloric Acid and 5 ml of Isopropanol to produce the Perchloric acid/Isopropanol Solution component previously provided in K555.

    3) Then follow the protocol for K555 available on www.biovision.com/documentation/datasheets/K555.pdf, using the components from this product, and the Perchloric acid/Isopropanol Solution that you produced.

     

    This product is manufactured by BioVision, an Abcam company and was previously called K226 Hydroxyproline Assay Kit (Perchlorate-Free). K226-100 is the same size as the 100 test size of ab222941.

    Hydroxyproline assay protocol summary:
    - add 10 N concentrated NaOH to samples and hydrolyze at 120ºC for 1 hr
    - cool on ice
    - neutralize with 10 N concentrated HCl, centrifuge and collect supernatant
    - add samples and standards to wells
    - evaporate wells to dryness by heating at 65ºC
    - add oxidation reagent mix to dissolve crystalline residue, and incubate at room temp for 20 min
    - add developer and incubate at 37ºC for 5 min
    - add DMAB concentrate and incubate for 45 min at 65ºC
    - analyze with microplate reader

    We are currently not able to offer K555 Hydroxyproline Colorimetric Assay Kit from BioVision and apologize for the inconvenience that this may cause. We recommend ab222941 as an alternative.

    Hydroxyproline, a non-essential amino acid derived from proline, with no known therapeutic use. Hydroxproline is used as a major component of structural protiens such as collagen, connective tissues, plant cell walls, tendons and ligaments and provides skin elasticity. Vitiman C is required for the conversion process from proline to hydroxyproline, a deficincy in vitiman C can lead to defects in collagen synthesis, thus, resulting in easy bruising, internal bleeding, breakdown of connective tissue of the ligaments and tendons, and increased risk to blood vessel damage. An unusual feature of this amino acid is that, it is not incorporated into collagen during biosynthesis at the ribosomal level, but is formed from proline by a posttranslational modification by an enzymatic hydroxylation reaction.

Porcine bone extracellular matrix quantification

Inconclusive Excellent 5/5 (Ease of Use)
Abreviews
Abreviews
Overall, the kit is very easy to use with a clear protocol.
My sample is lyophilized porcine bone extracellular matrix hence the sample was dry and required a preliminary step in order to perform the protocol. I followed the instructions for tissue lysates and took different amounts of ECM (10, 100 mg). Next, I tried different heating times with NaOH (1 or 2 hrs). Additionally, I performed the protocol on cardiac ECM for comparison.
In all the different attempts the ECM didn't fully dissolve, in some samples, there were still residues and in others, there was visible fat. Hence, the results of the protocol were Inconclusive and additional work should be done in order to develop a reliable dissolving protocol.

Compatilbility Issue

I was unable to use this kit to quantify hydroxyproline in my mouse sarcoma cell lines. The kit only has one plate sealing film which was inconvenient. Additionally, I was only able to detect the standards. All of my sample wells only had background. I tried adding ascorbate salt to my cells prior to harvesting, and I was still unable to detect hydroxyproline despite having increased collagen transcript and protein (immunoblotting) in my samples.

Straightfoward method to detect HYP - but not working on cell lysates!

Good Good 4/5 (Ease of Use)

I tried using this kit on 4T1 cell lysates. I incubated my cells with a P4HA1 inhibitor in order to see if i can detect any changes in HYP levels. unfortunately, HYP wasent detected even in the control samples. I used 10^6 cells with 100 DDW starting point but no almost no HYP was detected.
I wouldnt reccomend this kit for cells but it works for serum/media/tissue.

Absorption of collagen hydrolysate through zebrafish gills

Good Excellent 5/5 (Ease of Use)
Abreviews

abreview image
Collagen hydrolysate (CH) is a water-soluble substance, which together with the ability of fish to absorb compounds from the water through the gills [1], should allow its penetration. We tested the possibility of administering the drug to fish through water for absorption into the bloodstream. The fish were treated daily for a week with CH compound in three different doses: 10, 20 and 40 mg/L, compared with a control group (without CH). To assess the amount of CH in the serum, blood was extracted and hydroxyproline (HYP) was detected by using Hydroxyproline Assay Kit according to manufacturer’s protocol.
The values obtained were lower than the values of the calibration curve, these results can be explained by two possible reasons, it is possible that the material is not absorbed by the fish. Another possibility is that the values are lower than the identification threshold of the kit.
