A protein found in uncooked egg white that binds to and inactivates biotin. An abundance of ''.

抗生物素蛋白卵清中发现的一种蛋白质，它可与生物素结合并使生物素活性减低。

Latest research indicates that,if eating a great deal of undone eggs for a long time,antibiotin protein in undone egg white can integrate with biotin internal the body as a sort of steady compound,making biotin can't be absorbed by intestinal wall and leading to energy ennui,muscle ache,hair falling off,skin inflamation,appetite letdown,weight droping and so on.When eggs pass through the intestinal tract,it's easy to zymolysis and transformation,sometimes it may appear nitroso compound,which has the function of causing cancer.

最新研究表明，若长期大量吃生鸡蛋，生鸡蛋清内的抗生物素蛋白与体内生物素结合成一种稳定的化合物，使生物素不能被肠壁吸收，则可导致精神倦怠、肌肉酸痛、毛发脱落、皮肤发炎、食欲减退、体重下降等；生鸡蛋经过肠道时，容易发酵变质，有时可能产生亚硝基化合物。

The liquid absorption value and growth of the bacillus was measured after 24, 48 and 72 hour. It was showed that the most effective level of maltose in the medium is 5%. The media with pimelic acid was centrifugated 30min at 10000r/min, room temperature

本研究还将添加5%的麦芽糖的生物素培养基分组，分别加入0、0.2、0.4、0.6、0.8、1.0、1.2、1.4、1.6、1.8、2.0g/L的庚二酸，接种，在37℃，220r/min条件下进行振荡培养，然后测定24、48和72h时菌液的吸收值、pH值、生物素和庚二酸含量，确定庚二酸添加量为1.0g/L时，培养液中的生物素产量最大，庚二酸利用率最高。

The present dissertation reviews the total synthesis of biotin, particularly on Hoffmann-La Roche\'s Lactone-Thiolactone approach. The Lactone-Thiolactone approach is presently the most competitive commercial route, which gives an excellent illustration of the gradual construction of the functionalized skeleton with the simultaneous solution of the stereochemical issues in a minimal number of steps.In 1970, Gerecke etc. of Roche Corp.

论文对生物素全合成的文献进行了综述，重点讨论了目前工业上最有竞争力的内酯—硫代内酯路线，展示了生物素是如何以最少的步骤去逐步构建目标产物的官能团骨架并同时解决立体化学问题的。1970年，Roche公司的Gerecke等报道了一条通过手性内酯，以较高收率并保持构型得到手性硫代内酯，从而直接合成d-生物素的方法后，该中间体内酯(3aS，6aR)-1，3-二苄基。

Biotinylated IGF-1 was complexed with tetravalent streptavidin and then bound to biotinylated self-assembling peptides.

首先用四价的抗生物素蛋白链菌素合成生物素化的IGF-1，然后和生物素化的自我组装的肽结合在一起。

A mandarin orange; a tangerine.A protein found in uncooked egg white that binds to and inactivates biotin.

抗生物素蛋白卵清中发现的一种蛋白质，它可与生物素结合并使生物素活性减低。

BQJ-34 was cultured on the biotin fermentation media for 48 hour ,a 10ml fluid medium was boiled for an hour and was centrifuged (10,000r/min , 30 min), the supernatant is filleted with the 0.22μm filters and the biotin content of filter liquid is detected by RP-HPLC based on the biological samples regression analysis, recovery, accuracy testing.

利用生物素培养基对菌株BQJ-34进行振荡培养，取48h的细菌培养液10ml置100℃条件下水浴1 h，随后在超速离心机上以10 000 r/min，30 min离心，取上清液用0.22μm滤膜过滤，用高效液相检测滤液中的生物素含量，并通过对生物素样品的回归分析和回收率、精密度试验，最终确定利用反相高效液相色谱法可用于培养液中生物素测定，其最佳检测条件是：用安捷伦Zorbax SB-C18(4.6~※250cm，5μm)色谱柱，以K_2HPO_4(0.04mol，pH2.5)和CH_3CN(二者体积比为91.5：8.5)为流动相，紫外检测波长为215nm。

Preliminary studies on affinity isolation based on the specific combination between Biotin and Avidin Presently, affinity chromatography is increasing to be a main protein isolation and purification technique for a complicated system because of its high specificity, high rate of recovery, etc.

利用生物素和抗生物素蛋白间的特异性结合作用，将生物素通过化学反应键合到蛋白质的某种官能团上，酶解后的肽段通过固定了抗生物素白蛋白的亲和分离凝胶色谱柱，可以选择性地分离生物素化的肽段，达到简化复杂体系的目的。

Methods The ELISA plate was firstly coated with Mycoplasma hyopneumoniae , and then successively incubated with rabbit anti Mycoplasma hyopneumoniae serum and goat anti rabbit IgG biotin to form the solid biotin, which competed with the biotin in the solution for the limited streptavidin horse radish peroxidase conjugate.

酶标板先用猪肺炎支原体包被，再依次用兔抗猪肺炎支原体抗血浆、羊抗兔IgG -生物素温育形成固态生物素，同溶液中的生物素竞争有限量的链霉亲和素 HRP。
