脑钠素/利钠肽抗体产品介绍 Brain natriuretic peptide (BNP) circulates in blood as a peptide hormone with natriuretic, vasodilatory and renin inhibitory properties. BNP is secreted predominantly by the left ventricular myocytes in response to volume expansion and pressure overload. BNP belongs to a family of structurally similar peptide hormones, which includes atrial natriuretic peptide (ANP), BNP, C type natriuretic peptide (CNP) and urodilatin. These peptides are characterized by a common 17 amino acid ring structure with a disulfide bond between two cystein residues. This ring structure shows high homology between different natriuretic peptides (eleven of the 17 amino acid residues are homologous in the ring of each of the natriuretic peptides). BNP is a 32 amino acid peptide with disulfide bond between the cysteine residues Cys10 and Cys26. In earlier studies it has been demonstrated that BNP concentration in blood increases with the severity of congestive heart failure. Quantitative measurement of BNP in blood provides an objective indicator of congestive heart failure severity.

Function : Cardiac hormone which may function as a paracrine antifibrotic factor in the heart. Also plays a key role in cardiovascular homeostasis through natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. Specifically binds and stimulates the cGMP production of the NPR1 receptor. Binds the clearance receptor NPR3.

Subcellular Location : Secreted.

Tissue Specificity : Brain and also in atria, but at much lower levels than ANP.

Similarity : Belongs to the natriuretic peptide family.

Database links : UniProtKB/Swiss-Prot: P16860.1

在纯化抗体时需要控制好几个指标，包括纯度、含量及抗体的抗原结合活性。

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。脑钠素/利钠肽抗体的量可通过测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。
