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.
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.

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.
復溶:
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.
儲存條件:
Store at -20°C/-80°C upon receipt, aliquoting is
necessary for
mutiple use. Avoid repeated freeze-thaw cycles.
保質期:
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.
貨期:
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.
注意事項:
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Alpha-L-fucosidase is responsible for hydrolyzing the alpha-1,6-linked fucose joined to the reducing-end N-acetylglucosamine of the carbohydrate moieties of glycoproteins.

Homozygous frameshift mutation in the FUCA1 gene causes both severe and mild fucosidosis. PMID: 29588375
alterations in plasma levels of FUCA-1 were significantly associated with chronic inflammatory and autoimmune disorders, both in children and adults PMID: 28808940
the down-regulation of FUCA-1 correlates with increased aggressiveness of the cancer type. This is the first report indicating that the down-regulation of FUCA-1 is related to the increased aggressiveness of thyroid cancer. PMID: 28404918
the possibility that the higher fucose levels on cell surface glycans of aggressive anaplastic thyroid cancer samples (ATCs), compared to those of less aggressive papillary thyroid cancer samples(PTC), may be at least in part responsible for the more aggressive and metastatic phenotype of ATCs compared to PTCs, as the expression levels of FUCA1 and FUT8 were inversely related in these two types of cancers. PMID: 28440416
whole exome sequencing and array-based comparative genomic hybridization analysis revealed that the patient was compound heterozygous for a single base-pair deletion inherited from his father, and a 3281-base-pair deletion covering exon 3 inherited from his mother. Neither mutation has been reported before so the FUCA1 mutational spectrum is herein expanded. PMID: 27706744
results show that protein defucosylation mediated by FUCA1 is involved in tumor suppression PMID: 26998741
FUCA1 downregulation confers inferior survival for triple-negative breast cancer patients by modulating the glycosylation status of the tumor cell surface PMID: 26204487
We observed significant lower values of GAL, alpha-fucosidase and tendency to decrease of MAN and GLU concentration in nasal polyps PMID: 23911047
Serum alpha-L-fucosidase levels were significantly elevated in hepatocellular carcinoma. PMID: 25129443
IL-13, IL-4 and IL-5 have no effect on the expression of FUCA1 and FUCA2, but its expression is upregulated by IFN-gamma, a Th1 cytokine. PMID: 24469468
Preoperative serum AFU is a prognostic predictor of hepatocellular carcinoma. PMID: 24569461
Diminished FUCA1 mRNA levels in tumors, indicate that expression of tissue alpha-L-fucosidase could be regulated at transcriptional level in colorectal cancer. PMID: 23965968
In the serum of patients with Lyme disease, GAL activity significantly increased (p = 0.029), and the activity of FUC had a tendency to increase (p = 0.153), compared to the control group. PMID: 22763966
Data show that the correlation between the fluorescence activity of the enzyme AFU by the developed procedures and the standard method was positive and highly significant in patients and controls. PMID: 19782187
The purified alpha-L-fucosidase from primary hepatocarcinoma (PHC) is different in its properties from alpha-L-fucosidase in human other organs. The polyclonal antibody prepared in this experiment can be applied to the diagnosis of PHC. PMID: 16773698
The fucosidase has a role in the intimate species signature interactions between sperm and oocyte. PMID: 17133604
following HIV infection, there is an increased rate of catabolism of glycoconjugates in saliva resulting from changes in the proportions of the activity of isoenzymes A and B of N-acetyl-beta-hexosaminidase, beta-galactosidase and alpha-fucosidase PMID: 18217416
