• Relevance:

  Mediates the entry of L.monocytogenes into host intestinal epithelial cells; transformation with inlA alone allows L.innocua (a non-invasive species) to be taken up by host cells (PubMed:1905979, PubMed:8601315, PubMed:10406800). Binds to human receptor cadherin-1 (E-cadherin, CDH1); the chicken homolog of cadherin-1 but not cadherin-2 function as receptors (PubMed:8601315). Mouse cadherin-1 is not a receptor, however mutating a single surface-exposed residue (Glu-172 to Pro in mouse) allows cadherin-1 to act as a receptor for InlA (PubMed:10406800).

• Purity:

  Greater than 85% as determined by SDS-PAGE.

• Activity:

  Not Test

• Length:

  Partial

• Form:

  Liquid or Lyophilized powder

• 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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

• Molecular Weight:

  48.9 kDa

• Storage Conditions:

  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℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.
