英文介绍：HLA-DQB2 belongs to the family of HLA class II beta chain paralogs. Class II molecules are heterodimers consisting of an alpha (DQA) and a beta chain (DQB), both anchored in the membrane. They play a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). Polymorphisms in the alpha and beta chains specify the peptide binding specificity, and typing for these polymorphisms is routinely done for bone marrow transplantation. However this gene, HLA-DQB2, is not routinely typed, as it is not thought to have an effect on transplantation. There is conflicting evidence in the literature and public sequence databases for the protein-coding capacity of HLA-DQB2. Because there is evidence of transcription and an intact ORF, HLA-DQB2 is represented in Entrez Gene and in RefSeq as a protein-coding locus.

Anti-HLA-DQB2抗体,组织相容性抗原DQB2抗体免疫组化操作流程
1 脱蜡和水化：脱蜡前应将组织芯片在室温中放置60分钟或60℃恒温箱中烘烤20分钟。 a 组织芯片置于二甲苯中浸泡10分钟,更换二甲苯后在浸泡10分钟
b 无水乙醇中浸泡五分钟
c 95%乙醇中浸泡五分钟
d 75%乙醇中浸泡五分钟
2 抗原修复：用于福尔马林固定的石蜡包埋组织芯片：
A 抗原热修复
a 高压热修复 在沸水中加入EDTA（ph8.0）或0.01m*缓冲溶液（ph6.0）.盖上不锈钢锅盖，但不能锁定。将玻片置于金属染色加上，缓慢加压，是玻片在缓冲液中浸泡五分钟，然后将盖子锁定，小阀门将会升起来。10分钟后除去热源，置入凉水中，当小阀门沉下去后打开盖子。此方法适用于较难检测或核抗原的抗原修复。
b 沸热修复 电炉或水浴锅加热0.01*缓冲液（ph6.0）至95℃左右，放入组织芯片加热10-15分钟。
C 微波炉加热 在微波炉里加热0.01*缓冲液（ph6.0）至沸腾后将组织芯片放入，断电，间隔5-10分钟，反复1-2次。适用的抗原：
Bcl-2.Bax.AR.PR.C-fos.x-jum.z-kit.c-myc.E-cadherin.
ChromograninA.Cyclin.ER.Heatshock.Protein.HPV.Ki-67.MDMZ.P53.P34.P15.P-glycoprotein.PKC.PCNA.ras.Rb.等
B 酶消化方法 
常用0.1%*和0.4%*液。*使用前预热37℃，消化时间约为5-30分钟。适用于被固定遮蔽的抗原：包括 Collagen.GFAP.
Complement.Cytokeratin.C-erB-2.LCA.LN.等
