- SynonymLAIR1,CD305
- SourceMouse LAIR-1, Mouse IgG2a Fc Tag, low endotoxin (LA1-M5254) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Tyr 141 (Accession # Q8BG84-1).Predicted N-terminus: Gln 22Request for sequence
- Molecular Characterization
This protein carries a mouse IgG2a Fc tag at the C-terminus.
The protein has a calculated MW of 40.6 kDa. The protein migrates as 50-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 0.1 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

Immobilized Human Collagen I protein at 2 μg/mL (100 μL/well) can bind Mouse LAIR-1, Mouse IgG2a Fc Tag, low endotoxin (Cat. No. LA1-M5254) with a linear range of 1-10 ng/mL (QC tested).
- BackgroundLeukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) is constitutively expressed on the majority of human peripheral blood mononuclear leukocytes. LAIR-1 or CD305 is a transmembrane glycoprotein with a single immunoglobulin-like domain and a cytoplasmic tail containing two immune receptor tyrosine-based inhibitory motifs. LAIR-1 recruits SHP-1 and SHP-2 phosphatases upon activation, and cross-linking of the LAIR-1 antigen on natural killer (NK) cells results in strong inhibition of NK cell–mediated cytotoxicity. Functions as an inhibitory receptor that plays a constitutive negative regulatory role on cytolytic function of natural killer (NK) cells, B-cells and T-cells. Activation by Tyr phosphorylation results in recruitment and activation of the phosphatases PTPN6 and PTPN11. It also reduces the increase of intracellular calcium evoked by B-cell receptor ligation.Diseases associated with LAIR1 include Chronic Active Epstein-Barr Virus Infection and Palindromic Rheumatism.

55KDa与24KDa目的条带处的目的条带为什么成“小草”一样,旁边没有mark的话就没有条带,有mark就出现“小草”样的条带,请各位大神答疑解难?感激不尽
血清为去除纤维蛋白原后的无形成分,颜色微黄,透亮。
血清的基本成分是水,水中溶有蛋白质、脂肪、糖、无机盐、维生素等营养成分,也溶有人体代谢产物。血清中有抗体,这是被称作免疫球蛋白的蛋白质。
最好能说得具体点,小弟对此几乎一窍不通
谢谢
非常急!
谢谢各位
