英文名稱:Anti-Oxytocin antibody
中文名稱:催產(chǎn)素抗體
催產(chǎn)素抗體保存條件:Store at -20 °C for one year. Avoid repeated freeze/thaw cycles. The lyophilized antibody is stable at room temperature for at least one month and for greater than a year when kept at -20°C. When reconstituted in sterile pH 7.4 0.01M PBS or diluent of antibody the antibody is stable for at least two weeks at 2-4 °C.
催產(chǎn)素抗體,Anti-Oxytocin抗體抗原抗體反應(yīng):
一、抗原抗體反應(yīng)特點(diǎn)
1.高度特異性,特異性是抗原抗體反應(yīng)的zui主要特征,特定抗原決定簇只與特定抗體結(jié)合;
2.可逆性:抗原與抗體結(jié)合形成抗原抗體復(fù)合物的過程是一種動(dòng)態(tài)平衡, 其反應(yīng)式為:Ag+AbAg·Ab;
3.適當(dāng)濃度和比例;
4.敏感性:在測定血清中某一物質(zhì)的含量時(shí),化學(xué)比色法的敏感度為mg/ml水平,酶反應(yīng)測定法的敏感度約為5~10μg/ml,免疫測定中凝膠擴(kuò)散法的敏感度與酶反應(yīng)法相仿。
二、影響抗原抗體反應(yīng)的因素
1.電解質(zhì) :抗原抗體特異結(jié)合后,膠體粒便可發(fā)生脫水作用,此時(shí)易受電解質(zhì)影響,如有適當(dāng)濃度的電解質(zhì)存在就會(huì)使它們失去部分負(fù)電荷而相互凝聚,于是出現(xiàn)明顯的凝集或沉淀現(xiàn)象。
2.酸堿度:合適的pH為6-8。
3.溫度:37℃通常是抗原體反應(yīng)zui適溫度。

背景介紹:This gene encodes a precursor protein that is processed to produce oxytocin and neurophysin I. Oxytocin is a posterior pituitary hormone which is synthesized as an inactive precursor in the hypothalamus along with its carrier protein neurophysin I. Together with neurophysin, it is packaged into neurosecretory vesicles and transported axonally to the nerve endings in the neurohypophysis, where it is either stored or secreted into the bloodstream. The precursor seems to be activated while it is being transported along the axon to the posterior pituitary. This hormone contracts smooth muscle during parturition and lactation. It is also involved in cognition, tolerance, adaptation and complex sexual and maternal behaviour, as well as in the regulation of water excretion and cardiovascular functions.
