程序性死亡配体1抗体产品介绍 Programmed cell death 1 ligand 1(Programmed death ligand 1; PD-L1; PDCD1 ligand 1; B7 homolog 1; B7-H1; CD274) involved in the costimulatory signal, essential for T lymphocyte proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibit T-cell proliferation and cytokine production.
Function : Involved in the costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation and cytokine production.
Subunit : Interacts with PDCD1.
Subcellular Location : Isoform 1: Cell membrane; Single-pass type I membrane protein. Isoform 2: Endomembrane system; Single-pass type I membrane protein.
Tissue Specificity : Highly expressed in the heart, skeletal muscle, placenta and lung. Weakly expressed in the thymus, spleen, kidney and liver. Expressed on activated T- and B-cells, dendritic cells, keratinocytes and monocytes.
Similarity : Belongs to the immunoglobulin superfamily. BTN/MOG family.
Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
Contains 1 Ig-like V-type (immunoglobulin-like) domain.

纯度:在实验的任何阶段,确定抗体溶液纯度的最简单方法是取一部分样本进行SDS-PAGE电泳。凝胶可用考马斯亮蓝染色(灵敏度为0.1—0.5ug/带)或银染(灵敏度1~l0ug/带)。
定量:如果抗体还不纯,有一个快捷的定量方法,即通过SDS-PAGE电泳分离出轻、重链,然后和已知的标准染色带比较。如果需要分析许多样本,用免疫测定法对抗体定量较容易。如果抗体是经过纯化的,可通过测蛋白总量代替上述两种方法,有一简单的方法,即紫外吸收法。程序性死亡配体1抗体的量可通过测280nm处的吸收值来测(10D大致相当于0.75mg/m1的纯化抗体)。
抗原结合活性:一般说来,纯化方法不会引起抗原结合活性的改变。用蛋白G或蛋白A树脂很少导致抗体活性丧失。然而,如果最终抗体产物的作用不如原来所预料的好,检测抗体纯化过程所丢失的活性就极为重要。用一系列滴定法比较纯化的抗体和其原材料的活性,以标定每一步中的总抗体量,这将有助于较好的估计通过纯化所丢失的活性。
