Periostin (OSF-2) is secreted as a 91 kDa homodimeric soluble extracellular matrix protein expressed in collagen-rich fibrous connective tissues. There are at least 7 isoforms of Periostin, caused by alternative splicing (//www.uniprot.org/uniprot/Q15063).
产品描述
Method
Sandwich ELISA, HRP/TMB, 12×8-well detachable strips
Sample type
Serum, plasma (EDTA, citrate, heparın), urine, cell culture supernatant
Sample volume
10 µl / well
Assay time
2 h / 2 h / 1 h / 30 min
Sensitivity
20 pmol/l (= 1 800 pg/ml)
Standard range
0 – 4 000 pmol/l (= 0 – 360 000 pg/ml)
Conversion factor
1 pmol/l = 91 pg/ml (MW: 91 kDa)
Specificity
Endogenous and recombinant human Periostin; all known isofoms.
Precision
In-between-run (n=10): ≤ 6 % CV
Within-run (n=5): ≤ 3 % CV
Cross-reactivity
Due to the high sequence homology between human Periostin and Periostin of other species there is potential cross-reactivity with cynomolgous monkey, dog and cat Periostin.
