Michel, P, Torkkeli, T, Karp, M & Oker-Blom, C 2001, ' Expression and purification of polyhistidine-tagged firefly luciferase in insect cells : A potential alternative for process scale-up ', Journal of Biotechnology, vol. 85, no. 1, pp. 49-56 . https://doi.org/10.1016/S0168-1656(00)00377-1
The coleopteran firefly, Photinus pyralis, luciferase was produced in lepidopteran Trichoplusia ni insect cells using a baculovirus expression vector. The recombinant protein was equipped with a polyhistidine affinity tag at the carboxyl terminus and

The capacity to saccharify barley grain mash of Hormoconis resinae glucoamylase P produced by a heterologous host, Trichoderma reesei, was compared with that of Aspergillus niger glucoamylase. The results showed that the glucoamylase P secreted by T.

The glucoamylase P gene of the fungus Hormoconis resiane has been cloned and sequenced from a genomic library. The gene consists of a 2153-bp protein coding region including three introns. The usual number of introns in cloned fungal glucoamylase gen

An Aspergillus gene coding for a pH 2.5 acid phosphatase enzyme was successfully overexpressed in Trichoderma reesei under the strong main cellobiohydrolase I (cbh 1) promoter. The best transformants produced up to 240 times more of the acid phosphat

Secretion of the Hormoconis resinae glucoamylase P (GAMP) enzyme from Trichoderma reesei using either the natural N-terminal extension of the premature glucoamylase P or the cellobiohydrolase I (CBHI) signal peptide was examined. The expression condi

Uterine cytosol and nuclear receptors were measured at various time intervals after one dose or two consecutive doses of progesterone and the receptor values compared with the course of induction of uteroglobin, a progesterone-regulated uterine prote

Progestational activity of natural and synthetic androgens was examined. All the androgens studied were able to induce uteroglobin synthesis in rabbit uterus. Some of the synthetic androgens were better inducers than progesterone itself. The data sug

The Saccharomyces cerevisiae var. uvarum MEL1 gene, conferring production of α-galactosidase, has been cloned to study its expression. Increasing amounts of α-galactosidase protein and activity closely followed the induction of functional MEL1 tran

A radioimmunoassay (RIA) for blastokinin from rabbit uterine fluid has been developed using antisera raised in male guinea pigs against purified blastokinin. [ 125 I]Iodoblastokinin was prepared with a chloramine-T method and the separation of bound

Investigations were conducted to quantify activity of uteroglobin mRNA and secretion of uteroglobin in rabbit uterus after administration of progesterone and 5alpha-dihydrotestosterone, either alone or concomitantly with oestradiol-17beta and tamoxif
