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.
Probably involved in lipid transport. Can bind sphingosine-1-phosphate, myristic acid, palmitic acid and stearic acid, retinol, all-trans-retinoic acid and 9-cis-retinoic acid.

apoM-S1P-S1PR1 signaling might underlie the pathogenesis of ALI and apoM could have physiological benefits to alleviate LPS-induced ALI. PMID: 29260347
These S1P-induced enhancements in growth factors and chemotactic cytokines in retinal pigment epithelium cells were significantly inhibited by ApoM treatment. Additionally, in vivo experiments using a laser-induced choroidal neovascularization (CNV) murine model demonstrated that intravitreal ApoM injection significantly reduced the progression of CNV formation. PMID: 29301231
This study highlights the complexity of Apom/S1P in atherosclerosis and challenges the notion that the Apom/S1P complex is anti-atherogenic, at least in Apoe-deficient mice. PMID: 28866363
This suggests that the autophagy dysfunction caused by the deficiency of ApoM is an important factor in hepatic steatosis (triglyceride accumulation). ApoM plays a key role in normal autophagy activity in the liver and thereby further regulates the metabolism of liver lipids, particularly triglycerides. PMID: 29288662
HDL facilitates S1P efflux from erythrocytes by both apoM-dependent and apoM-independent mechanisms. Moreover, apoM facilitates tubular reabsorption of S1P from the urine, however, with no impact on S1P plasma concentrations. PMID: 24950692
The study suggests that vascular leakage of albumin-sized particles in ApoM deficiency is S1P- and S1P1-dependent and this dependency exacerbates the response to inflammatory stimuli. PMID: 26956418
apoM might facilitate the maintenance of CD4(+) T-lymphocytes or could modify the T-lymphocytes subgroups in murine spleen PMID: 26543853

ApoM augmented insulin secretion by maintaining the S1P concentration under both in vivo and in vitro conditions. PMID: 24814049
The present data indicate that the plasma apo-M levels modulate the ability of plasma to mobilize cellular cholesterol, whereas apo-M has no major effect on the excretion of cholesterol into feces. PMID: 24046869
ApoM can bind oxidized phospholipids, increasing the antioxidant effect of HDL. PMID: 22204862
Results show that apoM, by delivering S1P to the S1P(1) receptor on endothelial cells, is a vasculoprotective constituent of HDL. PMID: 21606363
After refolding from inclusion bodies, the crystal structure of apoM (reported here at 2.5 A resolution) displays a novel yet unprecedented seven-stranded beta-barrel structure. PMID: 20932978
apoM mainly associates with HDL in normal mice but also with the pathologically increased lipoprotein fraction in genetically modified mice; decreased apoM levels in apoA-I-deficient mice suggest a connection between apoM and apoA-I metabolism. PMID: 15102887
ApoM transcripts were detectable in mouse embryos from day 7.5 to day 18.5 PMID: 15147633

Based on these results, we suggest that insulin regulates apoM synthesis in vivo and, therefore, that the reduction of apoM expression is a general phenomenon in diabetes models. PMID: 16516154
