expressions of recombinant proteins for different applications are important objectives in molecular biotechnology; however, expression of some recombinant proteins is difficult. several methods have been designed for expression of these proteins. the aim of this study was to construct a vector containing mtb32c fragment of mycobacterium tuberculosis (m.tuberculosis) as a fusion partner in orde...

Given p ∈ (0, 1), we let be the random subgraph of d-dimensional hypercube Qd where edges are present independently with probability p. It is well known that, as d → ∞, if then high Qp connected; and consists one giant component together many smaller components which form “fragment”. Here fix , investigate fragment, how it sits inside hypercube. For example, give asymptotic estimates for mean n...

related to the relatively small number of total ions utilized for determining the mass spectra. CONCLUSION It would be a significant advance if the mass resolution of 1500 obtained with inorganic specimens could be retained with nonvolatile and thermally labile organic specimens as well as obtaining the structurally significant fragment ion signals. This advance will require more detailed studi...

A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) test was performed to investigate the allele frequencies of the insulin-like growth factor (IGF1 and IGF2 genes) in 90 broilerchickens. A 793 bp fragment of IGF1 gene and 1146 bp fragment of IGF2 gene were amplified and digested with HinfI and Hsp92II restriction enzymes,respectively. Two types of alleles of A and B...

We report the first experimental observation of nonadiabatic field-free orientation of a heteronuclear diatomic molecule (CO) induced by an intense two-color (800 and 400 nm) femtosecond laser field. We monitor orientation by measuring fragment ion angular distributions after Coulomb explosion with an 800 nm pulse. The orientation of the molecules is controlled by the relative phase of the two-...
