Fentanyl (FYL) Detection Kit (Rapid Lab) is a lateral flow chromatographic immunoassay for the qualitative detection of Fentanyl/Norfentanyl in liquid and powder substances at the cut-off concentration of 200 ng/mL.
It is specific for Fentanyl screening with no significant cross reactivity to other opiates, such as Morphine and Heroin.
Interpretation of test results are: positive (one line), negative (two lines), invalid (no lines or no control line).
For professional institutions use only, not for self-testing.

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)
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.
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.
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.
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).

110 in total (allows a maximum of 48 samples to be run in duplicate alongside a standard curve).
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.
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.
