Frequently Asked Questions

Conventionally, immunohistochemical staining has been performed on whole tissue sections. However, this traditional method, which requires the processing and staining of hundreds or even thousands of slides, is time-consuming and expensive. In contrast, a TMA allows simultaneous analysis of hundreds of tissues in one go using identical conditions. Thus, TMA technology markedly conserves reagents, saves time and greatly decreases the amount of archival tissue required for a particular study, thus preserving the tissues for other diagnostic and/or research needs.

A core size of 0.6 to 2.0 mm is adequate to represent the whole tissue section.

Sometimes, a small core of sample may not be representative of the whole tumour, especially in heterogenous tumour types. To overcome this, we offer TMAs that include two to three cores of samples from different locations of a single tumour block.

Negative and positive control TMA slides should be included as they are important in ensuring the validity of the experiment.

To help with TMA orientation.

A minimum of 3 slides per TMA type to include positive and negative controls.

All patients are anonymised.

Yes. You may contact us for further details and discuss on your needs.

The TMAs are sent in ambient temperature.

We recommend you to store your TMA slides at 4°C for not more than a year.
