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.

Description

The Biocolor Fastin™ Elastin Assay is a quantitative dye-binding method for the analysis of elastins released into tissue culture medium and extracted from biological materials.

The dye label employed is 5,10,15,20-tetraphenyl-21H,23H-porphine tetra-sulfonate (TPPS).

Elastin forms that can be measured by the Fastin Assay as α-elastin:

  1. soluble tropoelastins;
  2. lathyrogenic elastins;
  3. insoluble elastins (following solubilization to elastin polypeptides [α-elastin, κ-elastin])

The dye reagent binds to the ‘basic’ and ‘non-polar’ amino acid sequences found in mammalian elastins. For analysis of soluble elastin, samples should be free of any particulate material (cell debris, insoluble extracellular matrix material). The presence of other soluble proteins or of complex carbohydrates does not interfere with the Fastin Elastin Assay.

Principle of Method

Step 1. Incubation of samples containing soluble elastin with the Fastin Dye Reagent causes an elastin-dye complex to form. This insoluble complex then precipitates.

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).

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.

    Background

    Understanding Elastin: The Key to Tissue Flexibility:
    Tissues such as lungs, heart and blood vessels need to be able to stretch and recoil repeatedly throughout an organism's life. The protein Elastin is largely responsible for this elasticity. Elastin is initially secreted by elastin-producing cells as a soluble monomeric precursor known as tropoelastin. This undergoes a process of self-assembly and cross-linking with other extracellular matrix components that results in the formation of "insoluble" elastin fibers.
