Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Alkaline phosphatase that can hydrolyze various phosphate compounds.
Gene References into Functions
  1. Data confirm that, in enterocytes (Caco-2 cells), 1-alpha,25-dihydroxy-vitamin-D3 up-regulates expression of 2 isoforms of IAP, alternative splicing variants. PMID: 28931466
  2. Expressions of human intestinal alkaline phosphatase and sucrase-isomaltase, which are intestinal differentiation markers, were highly enhanced in Caco-2 cells by menaquinone-4. PMID: 27865621
  3. Data indicate alkaline phosphatase (AP) as the primary soluble ectonucleotidase in infants undergoing cardiopulmonary bypass and show decreased capacity to clear AMP when AP activity decreases post-bypass. PMID: 27384524
  4. Intestinal alkaline phosphatase is a major regulator of gut mucosal permeability and appears to work at least partly through improving tight junction protein levels and localization. PMID: 27106638
  5. A High Level of Intestinal Alkaline Phosphatase Is Protective Against Type 2 Diabetes Mellitus Irrespective of Obesity PMID: 26844282
  6. Review of the role of intestinal alkaline phosphatase in inflammatory diseases. Loss of IAP expression or function is associated with increased intestinal inflammation, dysbiosis, bacterial translocation and subsequently systemic inflammation. PMID: 27083970
  7. The expression of ALPi and MUC5AC in cocultures of Caco-2 and HT29 cells developed for permeability studies is reported. PMID: 26299896
  8. Data indicate that histone deacetylase inhibitors (HDACi) induce intestinal alkaline phosphatase (ALPi) in a subset of colon cancer cell lines in a Kruppel-like factor 5 (KLF5)-dependent manner. PMID: 25037223
  9. Report lowered intestinal alkaline phosphatase in the colonic mucosa of children with inflammatory bowel disease. PMID: 22783049
  10. we are the first to demonstrate the alteration of protein expression of iAP in the duodenal mucosa of children with newly diagnosed coeliac disease PMID: 22262031
  11. Mechanism of IAP action appears to be through dephosphorylation of specific bacterial components, including LPS, CpG DNA, and flagellin, and not on live bacteria. IAP likely targets these bacterially derived molecules as gut mucosal defense factor. PMID: 20489044
  12. the structural differences in human AP isoforms are demonstrated through models PMID: 12372831
  13. intestinal alkaline transactivation by Kruppel-like factor-4 is likely mediated through a critical region located within the proximal IAP promoter region PMID: 12919939
  14. Northern blotting detected expression of two IAP transcripts, which were increased approximately 3-fold in response to thyroid hormone PMID: 15143152
  15. receptor for Aeromonas sobria hemolysin PMID: 15715171
  16. Cdx1 activates the IAP gene via a novel cis element, whereas Cdx2 inhibits the Cdx1 effects PMID: 15774940
  17. Cotransfection with an HNF-4alpha expression vector demonstrated a direct activation of the ALPI promoter through -94 to -82 element PMID: 15831710
  18. Crohn's disease increases the alkaline phosphatase activity in the intestine. Use histochemistry to differentiate Crohn's disease/ulcerative colitis. PMID: 17498884
  19. has the ability to detoxify lipopolysaccharide and prevent bacterial invasion across the gut mucosal barrier. IAP expression and function are lost with starvation and maintained by enteral feeding PMID: 18292227
  20. Cathepsin C propeptide interacts with intestinal alkaline phosphatase (IAP) and heat shock cognate protein 70. The propeptide of cathepsin C may stimulate the sorting to the lysosome contributing to the degradation of IAP in Caco-2 cells. PMID: 18307834
  21. Suggest role for lysophosphatidylcholine in brush-border intestinal alkaline phosphatase release and restoration. PMID: 19407215
