支淀粉酶 amylopectin 除去淀粉中可溶性的直链淀粉后的难溶部分。曾称为α-直链淀粉，红直链淀粉（erythroamylose）。它与直链淀粉（20—25％）共同构成淀粉粒的主要成分，通常占75—80％。冷却时遇碘呈红褐色。在水中膨润，在热水中生成淀粉糊，它是D-吡喃葡萄糖以α-1，4键连结，均每24个有约1个末端葡萄糖残基的α-1，6-枝链出现，分子量约5万—100万的较大枝链分子。可被麦芽中的α-淀粉酶和β-淀粉酶切断α-1，4-键，水解释放出麦芽糖，但分解
liqiuling 怎么才能获取beta catenin的基因？ chuckdouble pubmed里面有Nucleotide.到那里找. liqiuling 不太会看，而且合成的话，很贵，想知道如果想获得别人的惠赠，该怎样做？哪位大侠支个招？不胜感激！ lmnsmu 在NCBI的核酸库中找到其序列，然后设计引物，通过RT-PCR扩增获得该基因
familar 小妹困惑，在此请教大师！ 做了几次beta-catenin的表达（western），都没做出来，目的蛋白的分子量是92，可是，做出来的印记总是在下方，明显的不是目的蛋白的位置。我师兄说，做beta-catenin要提核蛋白才能做出来，可我之前也有做出来过的！请教各位有经验的同志，这样的现象是何解？ woxingwosu 不一定要提核蛋白才能出来。b-catenin在核内核外都有分布。应该
