特异性
- This assay recognizes both natural and recombinant forms of the sCD44var(v6) molecule. To define the specificity of this ELISA, several structurally related and non-related polypeptides were tested for cross reactivity. Notably, there was no detectable cross reactivity with CD44-polypeptides lacking the protein sequence encoded by exon 6.
-
灵敏度
- The limit of detection for sCD44var(v6), defined as the analyte concentration resulting in an absorption significantly higher than the absorption of the dilution medium (mean plus two standard deviations) was determined to be 0.05 ng/mL (mean of 10 independent assays).

产品特性
- The Human sCD44var(v6) ELISA detects all circulating CD44 isoforms containing the sCD44var(v6) sequences. Determination of sCD44var(v6) will provide more detailed insight into different pathological modifications during cancer and other diseases.An anti-sCD44var(v6) monoclonal coating antibody is adsorbed onto microwells. sCD44var(v6) present in the sample or Calibrator binds to antibodies adsorbed to the microwells, a HRP-conjugated monoclonal anti-sCD44var(v6) antibody is added and binds to sCD44var(v6) captured by the first antibody. Following incubation unbound enzyme conjugated anti- sCD44var(v6) is removed during a wash step and substrate solution reactive with HRP is added to the wells. A colored product is formed in proportion to the amount of sCD44var(v6) present in the sample. The reaction is terminated by addition of acid and absorbance is measured at 450 nm. A calibration curve is prepared from six sCD44var(v6) Calibrator dilutions which allows determination of sCD44var(v6) concentration in samples.

注意事项
-
Since exact conditions may vary from assay to assay, a calibration curve must be established for every run.
Bacterial or fungal contamination of either screen samples or reagents or cross-contamination between reagents may cause erroneous results.

背景
- CD44 (Pgp-1, Ly-24, ECMR III, F10-44-2, H-CAM, HUTCH-I, In(Lu)-related p80, Hermes antigen, hyaluronan receptor) is a polymorphic glycoprotein which participates in a wide variety of cell-cell or cell-matrix interactions including lymphocyte homing, establishment of B and T cell immune responses, tumor metastasis formation and inflammation. Three isoform categories of the CD44 molecule have been identified: 1) a predominant 80-90 kDa category, the so-called standard form named C44std, 2) an intermediate size category of 110-160 kDa and 3) a category which includes very large isoforms of 250 kDa covalently modified by the addition of chondroitin sulfate. This CD44-family of transmembrane receptor molecules is derived from a single gene located on chromosome 11. Alternative splicing of the mRNA gives rise to the different isoforms, containing inserts of varying sizes in the extracellular domain of the molecule (exons v2-v10). All CD44 isoforms are variably glycosylated. In contrast to standard CD44 (CD44std) which is almost ubiquitously expressed, the variety of CD44 isoforms (CD44var) have a much more restricted distribution, e.g., on keratinocytes (exons v3-v10), epithelial cells (exons v8-v10), activated lymphocytes and macrophages (exon v6). A splice variant of CD44 (exons v4-v7) confers metastatic behavior in a rat carcinoma model, aberrant expression of splice variants has been detected on a variety of human tumor cell lines as well as primary and metastatic human tumors, including lymphomas, carcinomas (colon, thyroid, mamma, bladder), and gliomas.
