Collagen is a fundamental component of the extracellular matrix, and the predominant protein in animals, constituting around 30% of total protein mass. A glycoprotein, it is well known for its triple helical structure. This is formed from three polypeptide α-chains with Gly-X-Y repeating residues (Gly for Glycine, X for proline, and Y for hydroxyproline).
Over 28 types of collagens have been identified, with Type I collagen being the most abundant. It’s prevalent in ligaments, tendons, skin, and bone tissue. Its mature, insoluble form grants it remarkable strength, making it vital for the mobility of organisms. Collagen also has biochemical functions, influencing cell growth, proliferation, and differentiation.
This version of the kit is designed to detect and measure INSOLUBLE forms of collagen. Chose our Sircol 2.0 collagen kit if you need to analyse SOLUBLE collagen.
Collagen, with its diverse properties, finds utility in various industries. It plays a role in medicine for wound healing and has an expanding role in tissue engineering and cell culture for biomedical purposes. It’s gaining popularity in the cosmetic industry for skin rejuvenation and is used in chemical formulations and the food industry as a functional food supplement and additive.
Sircol dye reagent contains Sirius Red – a linear anionic dye with sulphonic acid side chain groups. Under assay conditions the Sircol dye binds the basic groups of soluble collagen molecules. Maximal binding occurs in collagens possessing intact triple helix organisation as the highly ordered Gly-X-Yn helical structure of tropocollagen further contributes to dye binding. This results in a high degree of dye-collagen specificity. Affinity is progressively reduced during heat denaturation 4ºC due to the unwinding of the triple helix and formation of random chains.
Step 1. Samples being assayed for insoluble collagen must first undergo a 2-3 hour pre-treatment with Sircol Fragmentation reagent. This converts insoluble collagen into water-soluble gelatin can then be assayed.
Step 2. Addition of Sircol Dye Reagent to these pre-treated insoluble collagen samples results in the formation of a denatured collagen-dye complex. This complex then precipitates during the dye incubation period and is subsequently isolated by centrifugation, followed by washing to remove unbound dye. The Denatured collagen-bound dye is then eluted and measured spectrophotometrically.
Step 3. The insoluble collagen content of unknown samples is quantified by comparison against a calibration curve prepared using a the denatured collagen standard supplied with the kit.
Assay range
100 – 1000 µg/ml
100µg/ml
Colorimetric Detection (556nm) (Endpoint)
110 in total (allows a maximum of 46 samples to be run in duplicate alongside a standard curve).
The assay can be used to assess the rate of production of newly laid down collagen fibres during periods of rapid growth, development, tissue repair, remodeling and wound healing. Sources of material includes tissues, bone and calcified tissue.
*Insoluble collagens must be converted into soluble form prior to assay. Instructions and regents are provided with the kit., depending on sample this will require prior salt/acid/acid-pepsin extraction.
**non-mammalian collagens may result in a reduced limit of detection. We recommend use of an assay standard matched to the species under assay.
Many customers have found that the straightforward sample processing and analysis of Sircol make it a good alternative to conventional hydroxyproline analysis.
This kit is designed for research use only. Not for use in diagnostic procedures.
Kit requires access to a centrifuge, water bath / heated block, as well as a spectrophotometer/colorimeter capable of absorbance detection at 556nm.
Specific sample preparation protocols may require customer to provide further reagents, consult assay manual for further information.

As collagens mature, they become increasingly crosslinked and insoluble – characteristics necessary for key biophysical role that collagen plays in living organisms. Biocolor’s Sircol™ INSOLUBLE Collagen Kit is a dye-binding assay designed for accurate quantification and measurement such collagens. It is ideal for analyzing crosslinked / insoluble collagens from sources such as tissues, bone, and calcified tissue.
Description
The ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) is a ready-to-use reagent with all the essential components for quantitative real-time PCR (qPCR) except primers and templates. The master mix contains a highly stable hot-start Taq polymerase in an optimized buffer with dsDNA specific SYBR green fluorescent dye. Consequently, the ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) features high stability during storage, even at 37°C for weeks. In addition to high sensitivity and signal intensity, the ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) performs a low background/ high specificity qPCR results, as well as a better compatibility with fast PCR program.
With inert smart blue contrast dye, the ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) is ready-to-use and greatly reduces pipetting errors, while largely improving the reproducibility of the process. The ExcelTaq™ 2X Fast Q-PCR Master Mix (SYBR, no ROX) is also compatible with ROX reference dye if ROX is recommended by the manufacturer of the qPCR system. This master mix allows sensitive, precise amplification, real-time tracking of the amplification process, and simultaneous quantification for targeted DNA molecules.

Norgen’s Saliva DNA Collection and Preservation Devices are designed for 1) simple and non-invasive saliva collection and 2) preservation of DNA in saliva samples at ambient temperature. Each of the 50 Saliva DNA Collection and Preservation Devices consists of 3 components:
Saliva samples are collected by spitting inside the Collection Funnel which has been assembled with the Collection Tube. After collecting the required volume of saliva the Collection Funnel is removed and the contents of the Preservative Ampoule are then added and mixed with the collected saliva. The Saliva Collection Tube is subsequently sent to the laboratory for DNA isolation and analysis. DNA can be isolated from the preserved saliva samples using Norgen’s Saliva DNA Isolation Kit (Cat. RU45400). Each of Norgen’s Collection Tubes is labeled with a unique serial number that can be used for secure and anonymous tracking of the sample. The saliva DNA in preserved samples is stable for more than 2 years at room temperature. This kit is ideal for collecting and preserving DNA samples for epidemiological and population studies.
Norgen’s Saliva DNA Preservative is an aqueous storage buffer designed for rapid cellular lysis and subsequent preservation of DNA from fresh specimens. The buffer prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the buffer eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperature. The components of the buffer allow samples to be stored for more than 2 years without any detectable DNA degradation.
Prior to saliva DNA isolation, vortex the Collection Tube containing preserved saliva for 10 seconds and incubate at 55°C for one hour. Saliva DNA can now be isolated from the preserved saliva samples using any commercially available method, including Norgen’s Saliva DNA Isolation Kit (Cat. RU45400), Norgen’s Saliva DNA Isolation 96-Well Kit (Cat. RU35200) and Norgen’s Saliva DNA Isolation Kit (Magnetic Bead System) (Cat. RU55400, RU62900). Also, Norgen’s Saliva DNA Isolation Reagent Kit (up to 4 mL) (Cat. RU35720) allows for DNA isolation from the preserved saliva samples using an alcohol precipitation method. The purified DNA is of the highest quality and can be used in a number of downstream applications including PCR, NGS and microarray analysis.
