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.
產品提供形式:
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.
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.
Receptor for neuropeptide Y and peptide YY. The activity of this receptor is mediated by G proteins that inhibit adenylate cyclase activity. Seems to be associated with food intake. Could be involved in feeding disorders.

NPY and agonists of Y2R and Y5R may be neuroprotective against oxygen-glucose deprivation-induced neuronal cell death in primary cortical cell cultures after delayed treatment. A Y2R agonist not only diminished transient cerebral ischemia-induced neuronal injury, but also improved functional outcome after delayed treatment. Y5 and especially Y2 receptors may be promising targets for neuroprotection against ischemic damage PMID: 28057538
long-term over-expression of NPY in paraventricular nucleus contributes to the establishment of adipose tissue insulin resistance, at least partly via the Y5 receptor PMID: 25993471
Our results showed the altered expression of NPY, Y1R and Y2R but not Y5R in hippocampus and temporal lobe cortex of tremor rat brain. PMID: 24444822
Y5R does no tparticipate in the anorectic response to phenylpropanolamine. PMID: 23179670
results suggest that while signals mediated through NPY Y1 receptors play a modest role in reinstatement, activation of Y5 receptors has a critical function in food deprivation-induced reinstatement of heroin-seeking behavior. PMID: 21629996
the inhibition of central Y5 neurotransmission resulted in activation of thyroid axis during fasting suggesting that NPY-Y5 receptors contribute to fasting-induced TSH and TH suppression PMID: 21771616

via a specific Y-1R/Y-5R interplay, NPY acts as a neuroimmune co-transmitter in vivo. PMID: 12417430

data confirm the importance of both neuropeptide Y1 and Y5 receptors in the neuropeptide Y-mediated increase in food consumption and demonstrate that both receptors can mediate inhibitory effects of neuropeptide Y on the hypothalamo-pituitary-thyroid axis PMID: 12446577
Comparative mapping of Y1 and Y5 receptor subtypes within cell bodies and nerve fibers in the brain which, together with physiological and electrophysiological studies, provide a better understanding of NPY neural circuitries. PMID: 12900925
decreased expression and number of Y(5) receptors in the hypothalamic paraventricular nucleus cannot explain the attenuated responsiveness of the senescent rats to exogenous neuropeptide Y PMID: 15044185
we investigated the regulation of BDNF and NPY mRNA and Y1-, Y2-, and Y5-like receptor binding in the hippocampus of vehicle-pretreated, partially and fully amygdala-kindled rats and corresponding levetiracetam-pretreated rats (40 mg/kg i.p.). PMID: 15123022

Results describe the distribution of neuropeptide Y Y5 receptor-like immunoreactivity in the rat brain. PMID: 16954600
Selective stimulation of Y(5) receptor provokes activation of the HPA axis and its downstream pathway is chiefly composed of both CRF (primary regulator) and AVP (subordinate to the former) with distinct relative contribution. PMID: 17363455
These results suggest that in addition to regulating feeding behaviour, the Y5 receptor subtype may have previously unrecognised roles in the control of nesting behaviour during lactation with subsequent effects on litter growth rates. PMID: 19419662
