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.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
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.
and FAQs
Protein 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

Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate.
Gene References into Functions
  1. Data show that a protective conformational epitope is located in the head of Neisserial adhesin A (NadA). PMID: 25404323
  2. The prevalence and genetic diversity of pilE and nadA were investigated in the prevalent serogroups and clonal complexes of N. meningitidis isolated in China. PMID: 23290624
  3. The authors demonstrate by reporter gene fusion assays that alterations of the FarR binding site within the nadA promoter are sufficient to induce transcription of nadA. PMID: 21292554
  4. Our results suggest that NadA expression is under both stochastic and tight environmental-sensing regulatory control PMID: 20041170
  5. NmFarR is a negative transcriptional regulator of the adhesin/invasin NadA. PMID: 19400792
