A preliminary crystallographic study of recombinant human interleukin 1 beta.

Crystallization and preliminary crystallographic analysis of recombinant human calcyphosine.

Human calcyphosine was cloned into the pET-28a vector and highly expressed in Escherichia coli BL21 (DE3) cells. The protein was purified and crystallized. The crystal diffracted to 2.8 A and belonged to space group P2(1)2(1)2, with the unit cell parameters a=70.39 A, b=132.02 A, c=46.20 A.

Crystallization and preliminary X-ray crystallographic study of interleukin-8.

Interleukin-8 (neutrophil-activating factor; NAP-1) has been crystallized by the vapour diffusion technique to give single crystals suitable for three-dimensional structural study at a resolution higher than 2.4 A. The crystals belong to the space group P3(1)21 or P3(2)21 and have unit cell dimensions a = b = 40.9 A, c = 90.3 A.

effects of first language on second language writing-a preliminary contrastive rhetoric study of farsi and english

to explore the idea the investingation proposed, aimed at finding whether the performances of the population of iranians students studying english in an efl context are consistent in l1 and l2 writing taks and whether there is a cross-linguistic transfer in this respect. in this regard the subjects were instructed to write four compositions-two in english and two in farsi-which consisted of an ...

A phase I study of recombinant interleukin 2 plus recombinant beta-interferon.

Interleukin 2 (IL-2) therapies have antitumor activities against several neoplasms. In vitro these activities are enhanced by beta-interferon (IFN-beta). Therefore, we initiated a Phase I trial with a combination of IL-2 and IFN-beta three times weekly. The IFN-beta was administered i.v. Initially, the IL-2 was administered s.c. However, neutralizing antibody to the IL-2 developed in five patie...
