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.

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

reference.
儲存條件:

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.

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Ligand for CD2. Might facilitate interaction between activated lymphocytes. Probably involved in regulating T-cell activation.

soluble CD48 levels were significantly elevated in patients with nonallergic asthma compared to control and to the allergic asthma cohort PMID: 30306094
mCD48 and sCD48 are differentially expressed in the peripheral blood of asthma patients of varying severity. sCD48 inhibits CD244-mediated eosinophil activation. These findings suggest that CD48 may play an important role in human asthma. PMID: 27859399
The present study provides further insights into the role of the 2B4-CD48 interaction in the fine regulation of CD8(+) T-cell effector function upon antigenic stimulation. PMID: 26860368
Data show that 2B4 not only can bind to CD48 in trans but also interacts with CD48 in cis by using the same binding interface. Also, the results demonstrated that constitutive phosphorylation of 2B4 occurs only in the presence of CD48, and that cis binding is sufficient to induce substantial levels of baseline phosphorylation. PMID: 27249817
Our data indicate sCD48 as a SEB-induced 'decoy' receptor derived from eosinophil and therefore as a potential anti-inflammatory tool in S. aureus-induced eosinophil inflammation often associated with allergy. PMID: 26836239
CD48 expression was increased in patients with a short disease duration compared to both controls and patients with longer disease duration. In patients with short disease duration, increased CD48 expression was associated with alveolar inflammation. PMID: 26926492
These data demonstrate the important role of CD48 in SA/exotoxins-eosinophil activating interactions that can take place during allergic responses and indicate CD48 as a novel therapeutic target for allergy and especially of AD. PMID: 25255823
Blockade of 2B4/CD48 interaction resulted in improvement in function via perforin expression and degranulation as measured by CD107a surface mobilization on HTLV-1 specific CD8+ T cells. PMID: 24505299
we propose that SLAMF2 engagement regulates adaptive immune responses PMID: 24670806
Monocyte-induced natural killer cell dysfunction was markedly attenuated by blocking CD48 receptor 2B4 on NK cells, but not by blockade of NKG2D and NKp30. PMID: 23225218
replication study of association of 2 SNPs in HERV-K18 and 19 tagSNPs in CD48 with schizophrenia (SZ)and type 2 diabetes (T2D) in patients with SZ in 2 Danish samples; no association was found with SZ or with T2D among individuals with SZ for any of the SNPs PMID: 22495247
Stimulation of CD48 induces rearrangement of signaling factors in lipid rafts, Lck-kinase activity, and tyrosine phosphorylation. PMID: 20833258
The ligand (CD48) of the 2B4 receptor can exert both activating and inhibiting signals; natural killer (NK) cells might be at risk for self-killing were it not for the inhibiting signals generated by the 2B4-CD48 interaction. PMID: 20164429
CM1-induced apoptosis is achieved via different initiation pathways, which are cell-type dependent PMID: 12072193
Signal-dependent adhesion of resting NK cells initiated by expression of ICAM-1 is greatly enhanced by coexpression of CD48, even in the absence of cytokines. PMID: 12496412
Engagement of natural killer (NK) cell receptor 2B4 by its counterreceptor, CD48, expressed on target cells leads to an inhibition in NK cytotoxicity independent of signaling lymphocytic activation molecule-associated protein (SAP) expression. PMID: 15356144
IL-18, IL-18 receptor alpha, and CD48 complex formation via glycosylphosphatidylinositol anchor glycan triggers binding to IL-18 receptor beta, and thereby induces intracellular signal transduction and IFN-gamma production. PMID: 15760905
Review of recent studies suggests an important role for interactions between 2B4 and CD48 in the course of T cell activation and proliferation PMID: 16081768
2B4 (CD244) can stimulate NK cell cytotoxicity and cytokine production by interacting with NK cell expressed CD48 and adds CD48 to the growing number of activating NK cell receptors PMID: 16585556
CD48 is an interleukin (IL)-3-induced activating receptor on eosinophils and may be involved in promoting allergic inflammation. PMID: 16785501
In conclusion, we cannot confirm a role of human endogenous retrovirus-K18 superantigen polymorphisms or of the CD48 CA repeat for type 1 diabetes susceptibility. PMID: 16866884
findings indicate that FimH induces host cell signalling cascades that are involved in E. coli K1 invasion of human brain microvascular endothelial cells (HBMEC) and CD48 is a putative HBMEC receptor for FimH PMID: 17222190
the mechanism of signal transduction by CD244 is to regulate FYN kinase recruitment and/or activity and the outcome of CD48/CD244 interactions is determined by which other receptors are engaged. PMID: 17599905
