Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form
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 before Lyophilization
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.
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
Delivery time may differ 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.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Potentially involved in docking of synaptic vesicles at presynaptic active zones. May mediate Ca(2+)-regulation of exocytosis acrosomal reaction in sperm.
Gene References into Functions
  1. genetic variations in STX1B, DNMT3A and CYP1A1 have roles in influencing warfarin maintenance dose PMID: 27740732
  2. Transcranial magnetic stimulation measures of motor cortex excitability show normal excitability in adult STX1B mutation carriers with a history of seizures. PMID: 29101845
  3. 529 adults (n = 325 European-Americans, 204 Egyptians) on a stable warfarin dose were genotyped for GGCX rs12714145 and rs10654848, FPGS rs7856096, and STX1B rs4889606. PMID: 26751406
  4. Findings suggested that STX1B rs4889603, FAM47E rs6812193 and SCARB2 rs6825004 do not confer a significant risk for Parkinson's disease PMID: 26224037
  5. The data of this study suggested that the STX1B polymorphisms are associated with Parkinson disease etiology. PMID: 25534083
  6. Data indicate that single nucleotide polymorphism (SNPS) in the 3'-untranslated region of the fucosyltransferase 1 (FUT1) gene and intron of the syntaxin 1B (STX1B) gene were the top hits for Kawasaki disease (KD) susceptibility. PMID: 25101798
  7. STX1B and the presynaptic release machinery may have a role in fever-associated epilepsy syndromes PMID: 25362483
  8. The STX1B-Delta transmembrane domain is characterized as the first nucleoplasmic syntaxin with no transmembrane domain. PMID: 18691641
