The phrase "a limited amount of samples" is correct and usable in written English.
It can be used when discussing the quantity of samples available for analysis or testing in various contexts, such as research or quality control.
Example: "Due to budget constraints, we can only analyze a limited amount of samples for this study."
Alternatives: "a restricted number of samples" or "a small quantity of samples".
A limited amount of samples with thousands of features, give rise to known issues, as data overfitting and multicollinearity.
However, we did not sequence PCR products amplified from rodents at other study sites because of a limited amount of samples.
Unfortunately, the expression of genes linked to aberrantly methylated DMRs could not be analyzed due to poor RNA quality, which was probably due to effects of chemotherapy and a limited amount of samples.
Nevertheless, traditional MHC genotyping approaches may remain an alternative to consider when a limited amount of samples is to be genotyped, as NGS is still expensive and many research groups do not have direct access to these technologies.
Because this was a sub-study of a larger diabetes-prevention trial (diaBEAT-it trial), we were able to access only a limited amount of samples from the participants, not enabling us to conduct an in-depth study of the regulatory mechanism.

Reverse phase protein microarrays (RPMA) are a technology platform designed for quantitative, multiplexed analysis of specific phosphorylated, cleaved, or total (phosphorylated and non-phosphorylated) forms of cellular proteins from a limited amount of sample.
This method predicts pixel values for a raster layer from a limited amount of sampled data points.
The quantitative disagreement of the two distributions observed in this figure could be caused by that the size distribution from TEM images being slightly modified because the present observations were based on a limited amount of sample and observed TEM images were random but in small numbers (here n = 114).
If a limited amount of sample was available, serum was diluted 1 4 and considered positive if titers were >32.
These tests could detect a large number of different T-cell epitopes requiring a limited amount of sample volume, without the need for in vitro stimulation [ 21– 23].
