Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info
The following tags are available.
N-terminal His-tagged
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.
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
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Acts as a 'third messenger' substrate of protein kinase C-mediated molecular cascades during synaptic development and remodeling. Binds to calmodulin in the absence of calcium.

  6. Polymorphisms in NRGN are associated with schizophrenia, major depressive disorder and bipolar disorder in the Han Chinese population. PMID: 26828755
  7. Neurogranin and YKL-40 are promising AD biomarkers, independent of and complementary to the established core Alzheimer's disease (AD) biomarkers, reflecting additional pathological changes in the course of AD PMID: 26698298
  8. These results confirm an increase in CSF Ng concentration in patients with AD as previously reported and show that this is specific to AD and not seen in a range of other neurodegenerative diseases. PMID: 26826204
  9. This report provides evidence to support larger and controlled traumatic brain injury clinical studies for NRGN validation and prediction of outcomes. PMID: 26025774
  10. Within-person levels of NGRN increased in cognitively normal participants but not in patients with later stage mild cognitive impairment or Alzhiemer's disease; NGRN may reflect presymptomatic synaptic dysfunction or loss. PMID: 26366630
  11. Cerebrospinal fluid neurogranin was increased in patients with Alzheimer's dementia, progressive mild cognitive impairment (MCI) and stable MCI compared with controls, and in Alzheimer's dementia and progressive MCI compared with stable MCI. PMID: 26373605
  12. neurogranin binds to alpha-synuclein in the human cortex, and this interaction decreases in Parkinson's disease along with the phosphorylation of neurogranin, a molecular process thought to be involved in learning and memory PMID: 25446004
  13. These findings help to clarify underlying NRGN mediated pathophysiological mechanisms involving cortical-subcortical brain networks in schizophrenia. PMID: 24386483
  14. Data indicate that neurogranin makes contacts with both the N- and C-domains of calmodulin that functionally leads to altered calcium binding kinetics. PMID: 24713697
  15. NRGN risk variants contribute to subtle changes in neural functioning and anatomy. PMID: 24098564
  16. Our results support an association between the NRGN gene and schizophrenia and a hypothesis that the NRGN gene may mediate the risk associated with schizophrenia via intellectual dysfunction. PMID: 23903071
  17. The influence of NRGN genotype on the neural correlates of memory encoding and retrieval is manifest in the cingulate cortex and is involved in hippocampal formation. PMID: 21799211
  18. single nucleotide polymorphism located upstream of the neurogranin (NRGN) gene has been identified as a risk variant for schizophrenia. PMID: 22856365
  19. This study demonistrated that multiple rare mutations in schizophrenia, and provides genetic clues that indicate the involvement of NRGN in this disorder. PMID: 22306195
  20. This study provides further evidence of the association of the NRGN gene with schizophrenia. PMID: 22461181
  21. The genome-wide associated genetic risk variant in the NRGN gene may be related to a small gray matter volume in the anterior cingulate cortex in the left hemisphere in patients with schizophrenia. PMID: 22253779
  22. Hippocampal activation diminished during the acquisition of contextual fear in healthy carriers of the genome-wide-supported risk variant for schizophrenia, rs12807809 in neurogranin. PMID: 21647148
  23. our study provides strong evidence that common exonic variation does not account for the genome-wide signi fi cant association between schizophrenia and variation at NRGN PMID: 21538840
  24. Elevated cerebrospinal fluid neurogranin levels together with Alzheimer disease biomarkers may reflect synaptic degeneration. PMID: 20875798
