EGAD00001007586	This submission consists of 15 volunteer FASTQs, split by chemistry: Chemistry v1.1: 7 FASTQ sets, one set for each volunteer (RA1-7) Chemistry v2: 16 FASTQ sets, two for each volunteer (RA8-15; FASTQ set 1: Gene Expression (GEX); FASTQ set 2: TCR enrichment (VDJ))	NextSeq 550	7
EGAD50000001801	Mononuclear cells were collected from synovial fluid of anti-citrullinated positive antibodies (ACPA)-positive rheumatoid arthritis patients (n=8) and ACPA-negative RA patients (n=8). Global cell types (i.e., no enrichment) were obtained from these cryopreserved synovial fluid mononuclear cells (SFMC) samples and immediately fixed and processed using the GEM-X Flex Gene Expression Reagent Kits (10x Genomics) according to protocol. Following Gel Bead-in Emulsion (GEM) generation, samples were processed using the standard manufacturer’s protocol. Once sequencing libraries passed standard quality control metrics, libraries were sequenced on an Illumina NextSeq2000 P4 100 cycle reagent kit with the following read structure: R1: 28, R2: 90, I1: 10, I2: 10. Libraries were sequenced to obtain a read depth greater than 10,000 reads/cell for gene-expression (GEX). FASTQ files are made available. More detailed information can be obtained in Argyriou A. et al, Annals of the Rheumatic Disease, 2025.	NextSeq 2000	1
