Détail du produit FABP3 Kit ELISA

Analytical Method: Quantitative

Attributs du produit: The Rabbit H-FABP ELISA is based on a solid phase enzyme-linked immunosorbent assay (ELISA). The assay system utilizes an affinity purified anti-rabbit H-FABP antibody for solid phase (microtiter wells) immobilization and a different anti-rabbit H-FABP antibody in the antibody-enzyme (horseradish peroxidase) conjugate solution. The test sample is allowed to react simultaneously with the antibodies, resulting in H-FABP molecules being sandwiched between the solid phase and enzyme-linked antibodies. After a 60-minute incubation at room temperature on an orbital shaker, the wells are washed with wash buffer to remove unbound-labeled antibodies. A solution of TMB Reagent is added and incubated for 20 minutes at room temperature, resulting in the development of a blue color. Color development is stopped by the addition of Stop Solution, changing the color to yellow, and optical density is measured spectrophotometrically at 450 nm. The concentration of H-FABP is proportional to the optical density of the test sample.

Information d'application

Plaque: Pre-coated

Préparation de l'échantillon:

Serum should be prepared from a whole blood specimen obtained by approved techniques. Plasma may be used also.

Procédure de l'essai:

1. Secure the desired number of coated wells in the holder.
   2. Dispense 100 µL of calibrators and samples into the appropriate wells.
   3. Add 100 µL of enzyme conjugate reagent into each well.
   4. Incubate on an orbital micro-plate shaker at 100 rpm at room temperature (18-25°C) for 60 minutes.
   5. Remove the incubation mixture by flicking plate contents into an appropriate Bio-waste container or using a plate washer.
   6. Wash the microtiter wells 5 times with wash solution. Preferably, a plate washer should be used with a wash of 5 x 400 µL.
   7. Strike the wells sharply onto adsorbent paper or paper towels to remove all residual droplets.
   8. Dispense 100 µL of TMB Reagent into each well. Gently mix for 10 seconds.
   9. Incubate at room temperature in the dark for 20 minutes.
   10. Stop the reaction by adding 100 µL of Stop Solution to each well.
   11. Gently mix for 30° Conds. It is important to make sure that all the blue color changes to yellow color completely.
   12. Read the optical density at 450 nm with a microtiter plate reader within 15 minutes. In the event that the high calibrator OD readings exceed the range of the spectrophotometer, absorbance values for all wells may be determined at 405 nm instead.

Calcul des résultats:

1. Calculate the average absorbance values (A450) for each set of reference calibrators, and samples.
   2. Construct a calibration curve by plotting the mean absorbance obtained from each reference calibrator against its concentration in ng/mL on linear graph paper, with absorbance values on the vertical or Y-axis and concentration on the horizontal or X-axis.
   3. Using the mean absorbance value for each sample, determine the corresponding concentration of H-FABP in ng/mL from the calibration curve.
   4. If available, PC graphing software may be used.

Restrictions: For Research Use only

Stockage

Stock: 4 °C/-20 °C

Stockage commentaire: The calibrator stock provided with the kit should be frozen at or below -20°C on receipt. The remainder of the kit should be stored at 4°C and the microtiter plate should be kept in a sealed bag with desiccant to minimize exposure to damp air. Test kits will remain stable until the expiration date provided that the components are stored as described above.

Date de péremption: The expiry date is stated on the label.

Détail du antigène

Antigène: FABP3 (Fatty Acid Binding Protein 3, Muscle and Heart (FABP3))

Autre désignation: H-FABP

Sujet: Fatty acid-binding proteins (FABP's) are a class of cytoplasmic proteins of about 15 kDa that bind long chain fatty acids and play an important role in fatty acid metabolism. Different types of FABP have been detected including Heart FABP (H-FABP), liver FABP and intestinal FABP. Human cardiac muscle has high content of FABP (10-20 mol % of cytoplasmic proteins) and H-FABP is a sensitive biomarker of myocardial necrosis that can be used to confirm or exclude a diagnosis of acute myocardial infarction (AMI) and for monitoring recurrent infarction in humans. In AMI, H-FABP is rapidly released from damaged cardiomyocytes into the circulation due to its solubility and small size. Human clinical studies indicate that H-FABP levels are significantly elevated above threshold within 3 hours of AMI and subsequently return to normal values in 12 to 24 hours. H-FABP has also been identified as a potential serum biomarker for stroke that is superior to either neuron specific enolase or S100B. Our Rabbit H-FABP ELISA is offered as a tool for investigation of heart damage in rabbit models of cardiovascular disease.
