Rat Bax ELISA Kit

Description

Rat Bax ELISA Kit is a sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of rat Bax in serum, plasma, tissue homogenates, and other biological fluids.

Assay Type

Sandwich (quantitative)

Principle of Assay

Rat Bax ELISA Kit (A80253) employs the sandwich enzyme immunoassay technique for the quantitative measurement of rat Bax in serum, plasma, tissue homogenates, and other biological fluids. An antibody specific for Bax has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the Bax present in each sample is bound to the wells by the immobilized antibody. Following incubation, the wells are washed and then incubated with Biotinylated Anti-Bax Antibody, which binds the captured Bax present in each well. Following incubation, unbound biotinylated detection antibody is removed by washing, and an HRP-Streptavidin conjugate is added to the wells and the microtiter plate is incubated. Following incubation and washing, TMB substrate solution is then used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is proportional to the amount of Bax captured in each well. The concentration of Bax can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.

Required Materials

The following materials are not included in the kit, but are required to run this assay:

Microplate reader capable of measuring absorbance at 450nm ± 10nm.
Squirt bottle, multichannel pipette reservoir, or automated microplate washer.
Graph paper or computer software capable of generating logarithmic functions.
Test tubes and Eppendorf tubes to prepare standards and samples.
Multi- and single-channel pipettes and sterile pipette tips.
Deionized or distilled water.
Absorbent paper towels.
37°C incubator.

Important Notes

Sample concentrations should be estimated before being used in the assay and a proper dilution factor should be selected to make the diluted target protein concentration fall in the optimal detection range of this kit.
Sample matrix components will interfere with the test results. All samples must be diluted at least 1:2 with Sample Dilution Buffer.
Hemolysis can greatly impact the validity of test results. Take care to minimize hemolysis.
This ELISA kit is intended for the analysis of biological samples and has not been validated for purified/recombinant proteins, industrial, or commercial materials. Performance with such samples cannot be guaranteed, as differences in expression, sequence, tags, folding, post-translational modifications, purity, activity, or buffer composition may affect assay results. For further guidance, please contact our technical support team.

Bring all reagents and samples to room temperature before use.

We recommend that all standards and samples be assayed in duplicate.

Step 1

Prepare all reagents, samples, and working standards as directed in the previous sections.

Step 2

Determine the number of microplate strips required for the assay and insert them into the plate frame. Unused strips should be stored in the foil pouch at +4°C.

Step 3

Add 100μl of standard solutions to the standard wells. Note: A plate layout is provided to record standards and samples assayed.

Step 4

Add 100μl of samples to the sample wells. Note: All samples must be properly diluted in order to produce sample values within the dynamic range of the assay. All samples must be diluted at least 1:2 with Sample Dilution Buffer.

Step 5

Cover with an adhesive plate sealer provided and incubate at 37°C for 90 minutes.

Step 6

Remove the plate sealer, aspirate the liquid from the plate, and wash the plate two times with Wash Buffer. Soak wells with 350μl of Wash Buffer for 1-2 minutes each time. Note: Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Buffer by aspirating or decanting. Blot the plate onto paper towels or other absorbent material. Do not let the wells dry completely at any time!

Step 7

Add 100μl of Biotinylated Detection Antibody working solution to each well.

Step 8

Cover with a new adhesive plate sealer and incubate at 37°C for 60 minutes.

Step 9

Remove the plate sealer, aspirate the liquid from the plate, and wash the plate three times with Wash Buffer. Soak wells with 350μl of Wash Buffer for 1-2 minutes each time.

Step 10

Add 100μl of HRP-Streptavidin Conjugate (SABC) working solution to each well.

Step 11

Cover with a new adhesive plate sealer and incubate at 37°C for 60 minutes.

Step 12

Remove the plate sealer, aspirate the liquid from the plate, and wash the plate five times with Wash Buffer. Soak wells with 350μl of Wash Buffer for 1-2 minutes each time.

Step 13

Add 90μl of TMB Substrate to each well. Cover with a new adhesive plate sealer and incubate at 37°C in the dark for 10-20 minutes. Note: This incubation time is for reference only, the optimal reaction time should be determined by the end-user and can be shortened or extended according to the actual color change. The reaction may be terminated when a gradient is apparent in the standard wells. Do not exceed 30 minutes!

Step 14

Add 50μl of Stop Solution to each well. The color in the wells should change from blue to yellow immediately. Note: If the color in the wells is green or the color change does not appear uniform, gently tap the plate to ensure thorough mixing.

Step 15

Determine the optical density (O.D. value) of each well immediately using a microplate reader set to 450 nm.

Exercise training reinforces the therapeutic efficacy of bone marrow-derived mesenchymal stem cell transplantation for ventricular ectopy and myocardial infarction injury

This publication cites Rat Bax ELISA Kit (A80253).

Article Abstract

This study investigated the synergistic effect of early bone marrow-derived mesenchymal stem cells (BM-MSC) transplantation and endurance training on exercise-induced ventricular ectopy, myocardial infarction-induced injury and cardiac function in rats. 90 male Wistar rats (7-8 weeks) randomly distributed following groups, 1: Healthy control (HC, n = 15), 2: Sham (Sham, n = 15), 3 Myocardial infarction (MI, n = 15), 4: Myocardial infarction with BM-MSC transplantation (MI-SC, n = 15), 5: Myocardial infarction with Endurance training (MI-ET, n = 15) and 6: Myocardial infarction with Endurance training and BM-MSC transplantation (MI-ET + SC, n = 15). Myocardial infarction was induced by permanent obstruction of the cardiac left anterior descending artery. One day after MI induction, 1 × 10⁶ BM-MSC were injected via a caudal vein in MI-SC and MI-ET + SC groups, and training rat subjects were to run on a rodent treadmill for 10 weeks. BM-MSC alone decreased serum LDH, CK-MB, left ventricular Bax, and infarction size, and promoted serum IL-10, cardiac function and exercise capacities. These effects would be stronger if cell therapy was combined with exercise training. Cell therapy insignificantly decreased TNF-a and promoted left ventricular Bcl-2, but cell therapy with exercise training significantly reduced TNF-a and promoted Bcl-2. Despite the greater reduction of cardiac arrhythmia after exercise in the MI-ET + SC group, there was no significant difference between the treatment groups. The results of this study showed that exercise training and BM-MSC transplantation synergistically promoted myocardial infarction-induced injury healing and reduced ventricular ectopy after exercise in myocardial infarction rats via inflammation and apoptosis reduction.
