抗体规律
(1)初次反应产生抗体:当抗原一次进入机体时,需经一定的潜伏期才能产生抗体,且抗体产生的量也不多,在体内维持的时间也较短。
(2)再次反应产生抗体:当相同抗原第二次进入机体后,开始时,由于原有抗体中的一部分与再次进入的抗原结合,可使原有抗体量略为降低。随后,抗体效价迅速大量增加,可比初次反应产生的多几倍到几十倍,在体内留存的时间亦较长。
(3)回忆反应产生抗体:由抗原刺激机体产生的抗体,经过一定时间后可逐渐消失。此时若再次接触抗原,可使已消失的抗体快速上升。如再次刺激机体的抗原与初次相同,则称为特异性回忆反应;若与初次反应不同,则称为非特异性回忆反应。非特异性回忆反应引起的抗体的上升是暂时性的,短时间内即很快下降。
同源盒蛋白MEIS3抗体,Anti-Meis homeobox 3抗体 产品详情:
Hox, Pbx and Meis families of transcription factors form heteromeric complexes and bind DNA through specific homeobox domains. Hox proteins are involved in regulating tissue patterning during development, and are also expressed in lineage- and stage-specific patterns during adult hematopoietic differentiation and in leukemias. The Hox proteins, which include paralog groups 1-10, have a low intrinsic binding affinity for DNA and are instead associated into cooperative DNA binding complexes with Pbx or the Pbx- related Meis proteins, which result in an enhanced Hox-DNA binding affinity and an increased selectivity for the binding site. Both Meis1 and Meis2 (also known as Meis-related gene 1 or Mrg1) are members of the TALE (“three amino acid loop extension”) family of homeodomain-containing proteins. In addition to binding with Hox proteins, Meis1 also forms heterodimers with the ubiquitously expressed Pbx proteins, including Pbx1, Pbx2 and Pbx3, and these complexes contain distinct DNA-binding specificities. Like Hox and Pbx proteins, Meis1 is implicated in oncogenesis, as it is overexpressed as a result of adjacent retroviral insertion in BHX-2 myeloid leukemias. Two Meis-related proteins, Meis2 and Meis3 (also designated Mrg1 and Mrg2, respectively), possess largely similar sequence identity with Meis1 and are expressed in normal tissues and myeloid leukemias. In the pancreas, Meis2 preferentially associates with Pbx1, and together they associate with the pancreas-specific homeodomain factor, Pdx1, to repress Pdx1-induced transcriptional activation.
