Provided are methods for the detection and diagnosis of sickle cell. The methods are based on the discovery that abnormal levels of selected analytes in sample fluid, typically blood samples, of patients who are at risk are supportive of a diagnosis of sickle cell. At least two new biomarkers for sickle cell are thus disclosed, Eotaxin and Monocyte Chemotactic Protein-1. Altogether the concentrations of eleven analytes provide a sensitive and selective picture of the patient's condition, namely, whether the patient is suffering from sickle cell. Other important biomarkers for sickle cell are described, including but not limited to IL-12p40, SHBG, MMP-9, Adiponectin, Haptoglobin, FGF basic, IgM, Growth Hormone, Factor VII. Kits containing reagents to assist in the analysis of fluid samples are also described.

A prerequisite of proteomics is the ability to quantify many selected proteins simultaneously. Fluorescent sandwich immunoassays on microarrays hold appeal for such studies, since equipment and antibodies are readily available, and assays are simple, scalable and reproducible. To attain adequate sensitivity and specificity, however, a general method of immunoassay amplification is required. Coupling of isothermal rolling circle amplification (RCA) to universal antibodies can be used for this purpose: RCA on a synthetic DNA circle is initiated by a complementary oligonucleotide attached to an anti-biotin antibody; single-stranded RCA product remains attached to the antibody, and is detected by hybridization of complementary, fluorescent oligonucleotides. 51 cytokines were measured simultaneously on microarrays with signal amplification by RCA with high specificity, femtomolar sensitivity and 4 log quantitative range. This cytokine microarray was used to measure secretion from human Dendritic cells (DCs) induced by lipopolysaccharide (LPS) or tumor necrosis factor-alpha (TNF-(alpha). Rapid secretion of inflammatory cytokines such as MIP-1beta, IL-8, and IP-10 was induced by LPS. Eotaxin-2 and I-309 were found to be induced by LPS, and MDC, TARC, sIL-6R, and sTNF-RI were found to be induced by TNF-alpha. Since microarrays can accommodate ~1000 sandwich immunoassays of this type, a relatively small number of RCA microarrays appears to offer a tractable approach for proteomic surveys.
