抗体的异质性。抗体的组成极为复杂,是由成千上万、多种多样的免疫球蛋白(Ig)分子所组成。这些Ig分子在形状、大小、结构以及氨基酸的组成和排列上,既相似,又有差别。由于有差别,它们的电泳活性就有很大的变化。
载脂蛋白B-mRNA编辑酶复合物3C抗体有货供应 品说明:
APOBEC proteins inhibit retroviruses by deaminating cytosine residues of viral RNA and DNA. The seven APOBEC3 genes or pseudogenes are found in a cluster thought to result from gene duplication on chromosome 22. Like APOBEC3G, APOBEC3F deaminates deoxycytosine to deoxyuracil in the minus strand of HIV-1 DNA, resulting in G to A hypermutation in the plus strand of DNA. Thus, APOBEC3G and APOBEC3F provide a mechanism for innate immunity to retroviruses, and are also likely contribute to sequence variation observed in many viruses. Viral infectivity factor (Vif) imparts APOBEC3G and APOBEC3F resistance to HIV through impaired translation of their mRNA and accelerated posttranslational degradation of the APOBEC3 proteins by the 26S proteasome. Interestingly, HIV-1 Vif cannot form a complex with APOBEC3G or APOBEC3F of mouse origin as it does with the human protein, and thus mouse APOBEC3G and APOBEC3F function as a potent inhibitors of wildtype HIV-1 replication, where human APOBEC3G and APOBEC3F are only able to inhibit Vif-deficient HIV-1 replication. This implies that induction of APOBEC3G and APOBEC3F activity or a method of blocking their interaction with Vif may provide a method for therapeutic intervention.
保存条件: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.

抗体结构:
抗体是具有4条多肽链的对称结构,其中2条较长、相对分子量较大的相同的重链(H链);2条较短、相对分子量较小的相同的轻链(L链)。链间由二硫键和非共价键联结形成一个由4条多肽链构成的单体分子。轻链有κ和λ两种,重链有μ、δ、γ、ε和α五种。 整个抗体分子可分为恒定区和可变区两部分。在给定的物种中,不同抗体分子的恒定区都具有相同的或几乎相同的氨基酸序列。可变区位于"Y"的两臂末端。在可变区内有一小部分氨基酸残基变化特别强烈,这些氨基酸的残基组成和排列顺序更易发生变异区域称高变区。高变区位于分子表面,多由17个氨基酸残基构成,少则只有2 ~ 3个。高变区氨基酸序列决定了该抗体结合抗原抗原的特异性。一个抗体分子上的两个抗原结合部位是相同的,位于两臂末端称抗原结合片段(antigen-binding fragment, Fab)。"Y"的柄部称结晶片段(crystalline fragment,FC),糖结合在FC 上。
