蛋白標簽:
N-terminal 6xHis-tagged
產品提供形式:
Liquid or
Lyophilized powder
Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
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.
緩沖液:
If the delivery form is liquid, the default storage buffer is
Tris/PBS-based buffer, 5%-50% glycerol. Note: If you have
any special requirement for the glycerol content, please remark
when you place the order. If the delivery form is lyophilized powder, the buffer before
lyophilization is Tris/PBS-based buffer, 6% Trehalose.
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:
Basically, we can dispatch the products out in 1-3 working days
after receiving your orders. 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.
May function as an inhibitor of the B-cell receptor signaling. May function in the B-cell-mediated immune response.

We conclude that these activated B cells are a component of the local autoimmune response, and through their RANKL expression, can contribute to joint destruction. Furthermore, their expression of FcRL4 and their enrichment in the IgA isotype points towards a potential role for these cells in the link between mucosal and joint inflammation. PMID: 28343748
intraepithelial FcRL4(+) B-cells are present in the salivary glands of pSS patients. These cells are likely involved in the epithelial changes seen in pSS. Their enrichment in parotid glands may explain why MALT lymphomas in pSS patients preferentially develop at this specific location. PMID: 28390747
Commercially available IRTA1 antibody can immunohistochemically distinguish MALT lymphoma from other low-grade B-cell lymphomas. PMID: 27666766
Significantly increased FCRL4 mRNA only in Graves disease patients but not in Hashimoto patients compared to normal controls. PMID: 25738996
The observed significant gene-environment interaction suggests that drinking and cooking oil use with FCRL4 gene polymorphism has a significant interaction. PMID: 25012527
we provide evidence for involvement of HCK and FGR in FCRL4-mediated immunoregulation and for the functional importance of posttranslational modifications of the FCRL4 molecule. PMID: 25972488
IRTA1 and T-bet are positive markers for the diagnosis of nodal marginal zone lymphoma PMID: 23855758
Data indicate that signaling by HIV-1 gp120 through integrin alpha4beta7 resulted in increased expression of the immunosuppressive cytokine TGF-beta1 and FcRL4. PMID: 24162774
The cytological features, growth pattern and IRTA1 positivity in nodal marginal zone lymphomas suggest they may derive from IRTA1(+) perifollicular B cells or monocytoid B cells detectable in reactive lymph nodes. PMID: 22716304
The FCRL4 polymorphisms may play an important role in the susceptibility and severity of ankylosing spondylitis in the Chinese Han population. PMID: 22777505
In cellular binding assays, as a bona fide receptor FcRL4 binds efficiently to immunoglobulin (Ig)A. PMID: 22491254
Data suggest that expression of FcRL4 in B-cells results in inhibition of BCR signaling at point of Syk phosphorylation by mechanism that involves phosphorylation of FcRL4 and its association with SHP-1/SHP-2. PMID: 21908428

Monocytoid B cells differ in their antigen profile (presence of IRTA1) from splenic and nodal marginal zone B cells. PMID: 16079106
