In one of my previous posts, I wrote about high density glass slide antibody arrays services.

Here, I’d like to focus on another antibody microarray product line, the C-series from Raybiotech, based on a membrane antibody array technology. Similar to western blotting – therefore very easy to process – they are suitable to most research laboratories for targeted protein profiling.

There are many, many ELISA tests out there to choose from, and making the best selection can sometimes be a bit daunting. In this post, let’s take a look at the key points to keep in mind.

In a previous post dedicated to Quantitative arrays (Quantibody), I introduced our L-Series aimed at a broad one shot profiling of up to 1000 markers at once. This relative quantitation technology allows you to perform a first screen of your samples of interest versus a control, before you go on to targeted profiling using either pathway specific arrays, or a custom array including the targets of interest identified with the initial L-series screen.

On your journey to Biomarker profiling, you will reach the point where you need to quantify the proteins of interest identified along the way (eg. validation of semi-quantitative array results; biomarker discovery with an initial hunch on which pathway is involved).

At this stage, you will have narrowed down the number of targets you want to look at. However, the use of ELISAs is likely to be still too costly, too time consuming, and may require too much sample volume.
