conjugate

biotin conjugate

form

lyophilized powder

composition

Lectin, ≥20%

extent of labeling

≥3 mol biotin per mol lectin

storage temp.

−20°C

Biochem/physiol Actions

LEA 不具有血型特异性,但对 N-乙酰-β- D -氨基葡萄糖低聚物具有亲和力。凝集素是一种糖蛋白,含有约等量的蛋白质和碳水化合物,并被报道抑制来自 菜豆的植物血凝素的促有丝分裂活性 。这种凝集素结合内皮细胞,用于显示微血管。

Physical form

含有 NaCl

Analysis Note

凝集活性以 μ 表示g/ml,并通过在 pH 7.3 的磷酸盐缓冲盐水中连续稀释 1 mg/mL 溶液测定。该活性是在 25℃ 下孵育 1 小时后凝集 2% 人红细胞悬液的最低浓度。

β1,3-N-acetylglucosaminyltransferases (B3GNTs) are Golgi-resident glycosyltransferases involved in the biosynthesis of poly-N-acetyl-lactosamine chains. They catalyze the addition of the N-acetylglucosamine to the N-acetyl-lactosamine repeat as a key step of the chain elongation process. Poly-N-acetyl-lactosamine is involved in the immune system in

NG2-glia, also known as oligodendrocyte precursor cells (OPCs), have the potential to generate new mature oligodendrocytes and thus, to contribute to tissue repair in demyelinating diseases like multiple sclerosis (MS). Once activated in response to brain damage, NG2-glial cells proliferate

Recently, a tumor model based on the chorioallantoic membrane (CAM) was characterized structurally with Magnetic Resonance Imaging (MRI). Yet, capability of MRI to assess vascular functional reserve and potential of oxygenation-sensitive MRI remain largely unexplored in this model. For this

We generated transgenic mice expressing bovine cellular prion protein (PrP(C)) with a leucine substitution at codon 113 (113L). This protein is homologous to human protein with mutation 102L, and its genetic link with Gerstmann-Sträussler-Scheinker syndrome has been established. This mutation
