MicroBioChips protein microarray and antibody microarray faq custom array
    • What is the goal of an antibody array experiment?
    • The goal of an antibody array experiment is to compare the expression level of hundreds of proteins simultaneously between samples; to characterize pathways or to identify biomarkers.

    • How many antibodies can I include per array?
    • It is possible to include around 100 diferent antibodies in duplicates on a 14-arrays slide. Around 500 in duplicates in a 2-arrays slide.

    • How many samples can I analyze?
    • On one slide, 14 different samples can be analyzed, as a function of experiment size.

    • What type of sample can I send?
    • MicroBioChips can work with cell pellet, tissue, cell culture supernatant, serum,…

    • What is the required quantity of starting biological material?
    • In order to realize the experiments in the better conditions,MicroBioChips needs at least: > 1 Million cells or 10mg of tissue, to extract and label >100µg of total protein extract; or 20 µl of serum.

    • How do you check antibody specificities ?
    • Most manufacturers attempt to verify antigen recognition for their antibodies. MicroBioChips can check this specificity in the presence of unsurpassed antigenic diversity and deliver a much higher level of confidence that your antibodies will perform the task envisaged without the risk of wasting valuable time and energy in the laboratory.

    • What type of controls do you include in the array?
    • In order to deliver the best results,MicroBioChips includes several controls: housekeeping proteins for normalization, labeled proteins for spotting, BSA for non-specific background.

    • What is the detection method ?
    • The detection method depends on the type of experiment, MicroBioChips utilize 2 diferent methods : direct labeling (with Cy5) and indirect labeling (sandwich method). To obtain more information visit our section Principle

    • Is microarray analysis method quantitative ?
    • The microarray method is semi-quantitative. But it is possible on demand, to include a standard curve for real quantification.

    • How many replicates shall I do ?
    • MicroBioChips highly recommends to conduct experiments on 3 or more replicates.
      If you wish to compare samples groups (e.g.: control versus test), it is recommended to have consistent biological samples and ideally group size able to facilitated meaningful statistical analysis.

    • What is the delivery time?
    • For custom microarrays it is about 6 to 8 weeks, depending on the complexity of a tailored experiments
