DBCO-PEG12-NHS Ester is a monodisperse PEG linker which enable free copper click chemistry with N3 group. NHS ester moiety can react specifically and efficiently with primary amines to form a covalent amide bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introducing the Fastin Assay Kit: Your Straightforward Solution for Elastin Quantification! Our user-friendly kit utilizes a dye-based method to measure elastin from in-vivo and in-vitro sources. It can be used to quantify various elastin forms, spanning from immature tropoelastin to mature, ‘insoluble’ elastin fibers.
Colorimetric Detection (513nm) (Endpoint)
Understanding Elastin: The Key to Tissue Flexibility
Tissues like lungs and arteries must maintain the ability to stretch and recoil repeatedly throughout an organism’s life. Elastin, a mature protein, is responsible for this elasticity and is usually present as insoluble fibers within the ECM. During development, these fibers are initially formed from a soluble precursor called tropoelastin.
What is the Fastin Assay?
The Biocolor Fastin assay is a user-friendly, dye-based means of quantifying elastins derived from both in-vivo and in-vitro sources. A variety of elastin forms can be assayed, from immature tropoelastin to mature ‘insoluble’ elastin fibres.
Further information on how the assay works can be found on the ‘Mode of Action‘ tab.
A list of suggested sample types can be found under the ‘Assay Specification‘ tab.
How does the Fastin assay detect Elastin?
The Fastin Dye Reagent contains an elastin-binding synthetic porphyrin, TPPS (5,10,15,20-tetraphenyl- 21H,23H-porphine). This affinity of TPPS for elastin was first observed when used as a ‘vital stain’ on live animals. Most tissues took up the dye initially but only elastin retained the TPPS molecules over time. [Winkelman, J. (1962), Cancer Res. 22, 589-596; Winkelman, J & Spicer, S. (1962), Stain Technol. 37, 303-305].
It has been proposed that the elastin binding of TPPS may be due to the retention of the acidic dye (which contains four charged sulfate groups) by the basic amino acid side chain residues of elastin.
How does the Fastin assay work?
Step 1. Incubation of samples containing soluble elastin with the Fastin Dye Reagent causes an elastin-dye complex to form. This insoluble complex then precipiates.
Step 2. Dye-labelled elastin is then isolated by centrifugation and the unbound dye removed. Elastin-bound dye is then eluted and measured spectrophotometrically.
Step 3. The elastin content of unknown samples can be calculated by comparison against a calibration curve prepared using a standard comprising water-soluble elastin (supplied with the kit).
Assay range
50 – 500µg/ml
Limit of Detection
50µg/ml
Detection Method
Colorimetric Detection (513nm) (Endpoint)
Measurements per kit
110 in total (allows a maximum of 48 samples to be run in duplicate alongside a standard curve).
Suitable Samples
In-vivo: tissues and fluids. Insoluble elastin will first require conversion to water soluble α-elastin using the oxalic acid reagents and extraction protocol supplied with the kit.
In-vitro: Elastin produced by cells during 2D/3D cell culture. NB elastin in conditioned cell media is typically below the detection limit of the kit.
Precautions
This kit is designed for research use only. Not for use in diagnostic procedures. Kit requires access to a centrifuge, heated water bath or block, as well as a spectrophotometer or colorimeter capable of absorbance detection at 513nm. Specific sample preparation protocols may require customer to provide further reagents, consult assay manual for further information.
Fastin elastin kit contents:
1. Dye Reagent (1x110ml)
2. α-elastin Reference Standard (1x5ml, 1.0 mg/ml soluble Bovine elastin)
6. 1.5ml micro-centrifuge tubes for dye-labelling reaction.
7. Assay kit manual

Principles
This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity DNA – can be used in sensitive downstream applications such as multiplex and quantitative pcr
Good repeatability – suitable for extracting high-yield DNA from insect tissue samples
Safe – without phenol chloroform extraction and alcohol precipitation

Storage and Stability
Proteinase K, RNase A should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2–8°C, but in thiscase buffers should be redissolved before use. Make sure that all buffers areat room temperature when used.
