Precision
Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of human SPRR2B in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

Function
(From Uniprot)
Cross-linked envelope protein of keratinocytes. It is a keratinocyte protein that first appears in the cell cytosol, but ultimately becomes cross-linked to membrane proteins by transglutaminase. All that results in the formation of an insoluble envelope beneath the plasma membrane.
Gene References into Functions
  1. Knockdown of the Sprr2b gene or inhibition of SPRR2B phosphorylation attenuates USP7/MDM2 binding and p53 degradation, leading to fibroblasts cell cycle arrest. PMID: 29581288
  2. An SNP in SPRR2B was predictive of asthma among white children with eczema from 2 independent populations. PMID: 22374195
  3. We showed that just four genes, G3BP2, SCARB2, CSNK1A1 and SPRR2B, can classify patients as presence of lymph node metastasis negative or positive, with 80.0% accuracy. PMID: 21985131
  4. SPR2B transcripts and protein were moderately increased in the human papillomaviurs 11- and 59-infected tissues. PMID: 14748073
Subcellular Location Cytoplasm
Protein Families Cornifin (SPRR) family
Tissue Specificity Suprabasal layers of squamous-differentiated tissues such as epidermis, esophagus, tongue and trachea.
