Lead Time
Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time maybe differs from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Usage
For Research Use Only. Not for use in diagnostic or therapeutic procedures.
When phosphorylated, plays a role in filament reorganization. Involved in the delivery of mutated CFTR to the plasma membrane. Involved in the uptake of thrombin-antithrombin complexes by hepatic cells. Together with KRT8, is involved in interleukin-6 (IL-6)-mediated barrier protection.

K18 deficiency of hepatocytes leads to steatosis, increasing with age, and finally to SH. K18 deficiency and age promote liver tumor development in mice, frequently on the basis of chromosomal instability, resembling human HCC with stemness features.PMID:27689336
K8/K18-dependent PKCdelta- and ASMase-mediated modulation of lipid raft size can explain the more prominent FasR-mediated signaling resulting from K8/K18 loss.PMID:27422101
autoantibodies were detected in aging K18-null male mice that had a related liver phenotype but normal colon compared with K8-null mice, suggesting that the autoantibodies are linked to liver rather than colonic diseasePMID:26399787
In human failing myocardium, where TNF-alpha expression is upregulated, K8/K18 were also ectopically expressedPMID:26280121

Data show that inhibition of extracellular signal-regulated kinase 1 and 2 (ERK1/2) activation sensitizes wild-type but not keratin 8 (K8)-null mouse hepatocytes to apoptosis, and is associated with a reduction in c-Flip protein, part of a K8/K18 complex.PMID:15282307
loss of the keratin cytoskeleton causes defects in the trophoblast giant cell layerPMID:15819413
K18 overexpression protects mice from Mallory body (MB) formation and from DDC-induced liver injury, which supports the importance of the K8-to-K18 ratio in MB formation.PMID:17187412
Study demonstrates here that, in the developing placenta of the mouse, the absence of the Mrj co-chaperone prevents proteasome degradation of keratin 18 intermediate filaments, resulting in the formation of keratin inclusion bodies.PMID:17409114
study shows that dominant mutation hK18 R89C, leads to cell type-specific lethality in mice, depending on ratio of mutant to endogenous keratins; a single, endogenous K18 allele rescued embryonic lethality but caused aggregation of keratinsPMID:17617404
Keratin absence or mutation is well tolerated after pancreatic but not liver injury, whereas excessive overexpression is toxic to the pancreas but not the liver when induced under basal conditions.PMID:18349119
Over expression of K18 R89C predisposes transgenic mice to thioacetamide- but not CCl(4)-induced liver fibrosis.PMID:18395095
