About ECOS 21 Competent Cells Strain: BL-21 (DE3)
This strain provides high level of protein expression. This strain
carries the lambda DE3 lysogen, which expresses T7 RNA polymerase from
the lacUV5 promoter by isopropyl-1-thio-ß-D-galactopyranoside (IPTG)
induction. The mutated rne gene (rne131) encodes a truncated RNase E
enzyme that lacks the ability to degrade mRNA, resulting in an increase
in mRNA stability. BL-21 is deficient in lon protease and the outer
membrane protease, OmpT. The lack of these proteases reduces degradation
of heterologous proteins expressed in the strain. The transformation
efficiency of BL-21 is usually low, so the 6 minute/ heat shock cold
plating protocol” is recommended if high efficiency is desired.ECOS 21
Competent Cells are chemically competent and have been developed using a
novel chemical preparation. ECOS technology makes the cell highly .
About ECOSTM 10B Competent Cells Strain DH10B

column. Contaminations like salts, metabolites and soluble
macromolecular cellular components are removed in washing steps. The
nucleic acids can be eluted in low salt buffer or water and are
ready-to-use in subsequent reactions.
The prepared nucleic acids are suitable for applications including real-time PCR/RT-PCR, automated fluorescent DNA sequencing, PCR, and many other enzymatic reactions. The detection limit for certain viruses depends on the sensitivity of individual PCR or RT-PCR assay. This protocol is recommended for parallel purification of viral RNA including HCV, HIV, and HTLV and viral DNA including HBV and CMV.

Ling-Zhi Immunomodulatory Protein
A large amount of the novelimmunomodulatory protein Ling Zhi-8 (LZ-8) is synthesized in the mycelia of
Ganoderma lucidum (Kino, K., Yamashita, A., Yamaoka, K., Watanabe, J., Tanaka,
S., Ko, K., Shimizu, K., and Tsunoo, H. (1989) J. Biol. Chem. 264, 472-478). A
cDNA and a gene for LZ-8 were isolated and characterized. The mixed
oligonucleotide probes for LZ-8 cDNA were designed from the results of protein
sequencing (Tanaka, S., Ko, K., Kino, K., Tsuchiya, K., Yamashita, A.,
Murasugi, A., Sakuma, S., and Tsunoo, H. (1989) J. Biol. Chem. 264,
16372-16377) and were used for screening the mycelial cDNA library. The nucleotide
sequence of the cloned cDNA confirms the amino acid sequence of LZ-8 that was
previously determined by protein sequencing. The clones containing the LZ-8
gene (lz-8) were obtained from the mycelial genomic DNA library using the cDNA
probe. Two CCAAT-like sequences and one TATA box were found at the upstream
region of the postulated transcription initiation site of lz-8. A small intron
(61 nucleotides long) divided lz-8 into two exons at the 5'-untranslated
region. The other characteristic sequences were also found around the
postulated transcription initiation site and around the poly(A) additional
site.
