Materials Required But Not Provided
- Microplate reader in standard size.
- Automated plate washer.
- Adjustable pipettes and pipette tips. Multichannel pipettes are recommended in the condition of large amount of samples in the detection.
- Clean tubes and Eppendorf tubes.
- Washing buffer (neutral PBS or TBS).
- Preparation of 0.01M TBS: Add 1.2g Tris, 8.5g NaCl; 450μl of purified acetic acid or 700μl of concentrated hydrochloric acid to 1000ml H2
- Preparation of 0.01 M PBS: Add 8.5g sodium chloride, 1.4g Na O and adjust pH to 7.2-7.
Typical Data Obtained from Human A2M/Alpha2-Macroglobulin PicoKine™ ELISA Kit
(TMB reaction incubate at 37°C for 15-25min)
Intra/Inter Assay Precision
|Intra-Assay Precision||Inter-Assay Precision|
Three samples with differing target protein concentrations were assayed using four different lots to measure the CV% lot to lot variance.
To assay reproducibility, three samples with differing target protein concentrations were assayed using four different lots.
|Lots||Lot1 (pg/ml)||Lot2 (pg/ml)||Lot3 (pg/ml)||Lot4 (pg/ml)||Mean (pg/ml)||Standard Deviation||CV (%)|
*The typical data is obtained from Boster's internal QC result and for reference only. It may differ from the lab test results of the end users. It is more important that the user's lab test results reflect the same linearity demonstrated in the typical data than achieving exactly the same O.D. values.

|Protein Function||Is able to inhibit all four classes of proteinases by a unique 'trapping' mechanism. This protein has a peptide stretch, called the 'bait region' which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase.|

|Background||Alpha-2-macroglobulin, also known as A2M or CPAMD5 is a large plasma protein found in the blood. This gene is mapped to 12p13.31. Alpha-2-macroglobulin is a protease inhibitor and cytokine transporter. It inhibits many proteases, including trypsin, thrombin and collagenase. A2M is implicated in Alzheimer disease(AD) due to its ability to mediate the clearance and degradation of A-beta, the major component of beta-amyloid deposits.

- Review by Preethi Vijayaraj
"Reasonable sensitivity and reproducibility"
--Preethi Vijayaraj, UCLA, Pediatrics, Postdoctoral Fellow
Application ELISA Sample Cell culture supernatant Detection --
"Our research focuses on in vitro modeling of organ fibrosis and drug discovery. The protocol for this product was easy to perform. However, there was some amount of variability with the replicates. Was effective in detecting A2M levels at pg levels. Reasonable sensitivity and reproducibility. Easy to use."
• Add tissue homogenates into the wells and then add ABC and TMB without adding any biotinylated detection antibody to see if any signal will be observed.
• If no signal is produced, then you can work on the tissue sample by using the kit.
The 1XTBS can be used if the pH value falls in the range of 7.2-7.6.
