sp3d2杂化:由一个ns、三个np轨道和二个nd轨道杂化形成六个能量等同的sp3d2杂化轨道。每个sp3d2轨道都含有1/6个s、1/2个p和1/3个d成分。构型为八面体。 杂化类型的判断方式 公式如下:(括号内为举例,以下均以H2S为例) k=m+n 当k=2 sp杂化 k=3 sp2杂化 k=4 sp3杂化 其中n值为AB...
( 1998 ) Assignment of Sp genes to rat chromosome bands 7q36 (Sp1), 10q31 q32.1 (Sp2), 3q24 q31 (Sp3) and 6q33 (Sp4) and of the SP2 gene to human chromosome bands 17q21.3 q22 by in situ hybridization . Cytogenet. Cell Genet. 81 , 273 – 274 ....
The hybridization signal was greatest for HUVEC probably since both cDNA probe and cell type were of human origin. Between the two bovine endothelial cell types, KDR expression was 2-fold greater in BREC than BAEC. This finding is consistent with our previous report that KDR receptor number is...
Hybridization profiles are shown Fig.7. All these genes were expressed in endothelial cells except ets-2, for which no signal could be detected even after a long exposure. Of note, low transcript levels of ets-2 were observed in human umbilical vein endothelial cells by Khachigian et al. (...
In the present -study, the genomic sequences and organization of CRSP1,2, iMid 3 were determined, and the expression of the genes in the porcine brain was investigated using in situ hybridization. Analysis of 5'-upstream regions of the three CRSPs demonstrated that CRSP1 and CRSP2 have ...
New 1D and 2D highly porous carbon allotropes are designed, which combine the atoms in sp1 and sp3 hybridization. The structural motifs of suggested compounds can emerge from the same polyyne building blocks as for experimentally fabricated expanded cubane. The structural, electronic properties and ...
