采用不同提取液，从洗涤过的巴西橡胶树橡胶粒子中提取蛋白质，并对其进行电泳分离与质谱鉴定。分离鉴定了2个含RicinB_Lectin_2结构域的糖基识别蛋白质，分别命名为HbRBLLP-1和HbRBLLP-2。这2个蛋白质可能是橡胶粒子膜蛋白质或是与橡胶粒子有较强的相互作用的蛋白质。对HbRBLLP-1及HbRBLLP-2进行生物信息学分析，结果表明它们的RicinB_Lectin_2结构域均仅有1个Q-x-W模体，而非蓖麻毒素B链所具有的(Q-x-W)3模体。

Proteins extracted with different buffers from washed Hevea brasiliensis rubber particles were subjected to electrophoresis and mass spectrometry analysis. Two carbohydrate binding RicinB_Lectin_2 domain containing proteins were isolated and identified, and these two proteins were designated as HbRBLLP-1 and HbRBLLP-2, respectively. These two proteins may be membrane proteins of rubber particles or proteins have a strong interaction with rubber particles. Bioinformatics analysis was also carried out on these two proteins. Bioinformatics analysis showed that HbRBLLP-1 and HbRBLLP-2 have only one QxW motif in their RicinB_Lectin_2 domain, respectively; whereas, ricin B chain has a (QxW)3 motif.
