Universal Lateral Flow Assay Kit (FAM-Gold)

Description

Carbendazim is a fungicide used for the treatment and control of fungal diseases. Carbendazim continues to be used, frequently in combination with other fungicides.

This kit is based on ELISA technology, which is fast, easy, accurate and sensitive compared with common instrumental analysis and only needs 1.5 hours in one operation, it can considerably minimize operation error and work intensity.

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.

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.
