Abstract: The present disclosure provides methods for conducting in situ multiplex and multi-omics detection and identification using coded padlocks probes. The methods comprise simultaneous use of RNA-specific padlock probes and polypeptide-specific padlock probes to detect both RNA and polypeptides in a cellular sample. Both types of probes include a barcode that unique identifies the RNA or polypeptide that that padlock probe detects. Both types of probes also include a batch-specific sequencing primer binding site to enable sequencing a desired subset of concatemer template molecules. Use of the batch-specific sequencing primers reduces overcrowding signals and images, to produces optical images that are intense and resolvable. By conducting multiple rounds of sequencing on the same cellular sample using different batch-specific sequencing primers enables multiplex and multi-omics sequencing to reveal numerous target RNAs and their encoded polypeptides.

Abstract: Image data analysis, and particularly identifying cluster or polony locations for performing base-calling in a digital image of a flow cell during DNA sequencing is described. A method may include generating a first plurality of flow cell images of a cellular sample immobilized on a support by conducting one or more cycles of sequencing reactions. The cellular sample may include a plurality of concatemer molecules therewithin. For the first plurality of flow cell image, pixel intensities, and a respective color purity of each of the pixel intensities may be determined. A base calling template may include base calling locations based on the pixel intensities and the respective color purity of the pixel intensities. The base calling template may be for registering a second plurality of flow cell images of the support in one or more subsequent cycles of the one or more cycles.
