The present invention and embodiments thereof relates to compositions and methods for storage, stabilization and preservation of biological samples and/or nucleic acids on a solid matrix. Methods for extracting, collecting, and recovering the biological samples and/or nucleic acids from the solid matrix are also described.

Methods are provided for determining a subtype of head and neck squamous cell carcinoma (HNSCC) of an individual by detecting the expression level of at least one subtype classifier selected from a group of genes that are relevant for determining HNSCC subtypes. Also provided herein are methods for determining a suitable treatment and predicting the overall survival and the likelihood of metastasis for the HNSCC patients according to their subtypes.

Kits and methods for single cell or multiple cell transcriptome analysis are provided. An adapter polynucleotide is disclosed which comprises a double-stranded DNA portion of 15 base pairs and no more than 100 base pairs with a 3single stranded overhang of at least 3 bases and no more than 10 bases, wherein the double stranded DNA portion is at the 5 end of the polynucleotide and wherein the sequence of the 3single stranded overhang is selected from the group consisting of SEQ ID NOs: 1-8 and 9, wherein the 5 end of the strand of the double-stranded DNA which is devoid of the 3single stranded overhang comprises a free phosphate.

The present invention is related generally to analysis of polynucleotides, particularly polynucleotides derived from genomic DNA. The invention provides methods, compositions and systems for such analysis. Encompassed by the invention are arrays of polynucleotides in which the polynucleotides have undergone multiple rounds of amplification in order to increase the strength of signals associated with single polynucleotide molecules.
