We have obtained two types of thermostable mutant lactate oxidase – one that exhibited an E-to-G point mutation at position 160 (E160G)through error-prone PCR-based random mutagenesis, and another that exhibited an E-to-G mutation at position 160 and a V-to-I mutation at position 198 (E160G/V198I)through DNA shuffling-based random mutagenesis – both of which we have previously reported.

The Hitachi SV1100 utilizes capillary electrophoresis on a microchip that is capable of rapidly sizing DNAfrag-ments. Reproducibility of electrophoresis in different channels was shown by comparing the migration times of the internal controls, DNAfragments of 100 and 800 bp. The range of DNAsizing for this microchip is between 100 and 800 bp, and accuracy in sizing of a 322 bp DNA fragment of a pUC118 PvuII digest was observed, inde-pendent of DNAconcentration. Although relatively good quantification of this fragment was observed with a DNA concentration of 1.

High-quality quantitative data generated under standardized conditions is critical for understanding dynamic cellular processes. We report strategies for error reduction, and algorithms for automated data processing and for establishing the widely used techniques of immunoprecipitation and immu-noblotting as highly precise methods for the quantification of protein levels and modifications.

In two cycles of an error-prone PCR process, variants of formate dehy-drogenase from Candida boidiniiwere created which revealed an up to 4.4-fold (440%) higher residual activity after entrapment in polyacrylamide gels than the wild-type enzyme. These were identified in an assay using sin-gle precursor molecules of polyacrylamide instead of the complete gel for selection.

The paper by S. Boronatet al. [1] contains errors on page 3331. The corrected sentence and corrected Figure 6 appear below: By contrast, the rainbow trout liver (RTL) cell line showed an EC50 for BNF of 6.1 ± 3.7 nm. These values increased to 53.4 ± 31.2 nmwhen the dose–response curve was performed in the presence of 200lmcarbaryl, indicating an antagonistic effect in these cells similar to the one observed for the yeast YCM-RYA system (Fig. 6; compare with Fig. 3).

Moreover, an investigation of the sampling variability of Hoxby’s estimates leads to the conclusion that her standard errors are understated, and that even her own point estimates of the competitive effect are not significantly different from zero....

GTP cyclohydrolase II catalyzes the first dedicated step in the biosynthesis of riboflavin and appears to be a limiting factor for the production of the vitamin by recombinantBacillus subtilisoverproducer strains. Using error-prone PCR amplification, we generated a library of theB. subtilis ribA gene selectively mutated in the GTP cyclohydrolase II domain.

Used to communicate IP status and error messages between hosts and routers Uses IP to route its messages between hosts Must be implemented with IP remember, IP is just a packet delivery system transmits and routes datagrams from sources to destinations through a series of interconnected networks it has a checksum in the IP header to detect lost bits no error detection on the datagram payload though but has no native mechanism for source host notification This is where ICMP comes in its used to report IP errors to the source host ICMP data is carried as the payload of an IP datagram specifie...

The delivery of a packet to a host or a router requires two levels of addressing: logical and physical. We need to be able to map a logical address to its corresponding physical address and vice versa. This can be done by using either static or dynamic mapping.

We develop an analogue for sphere packing of the linear programming bounds for error-correcting codes, and use it to prove upper bounds for the density of sphere packings, which are the best bounds known at least for dimensions 4 through 36. We conjecture that our approach can be used to solve the sphere packing problem in dimensions 8 and 24. Contents 1. Introduction 2. Lattices, Fourier transforms, and Poisson summation 3. Principal theorems 4. Homogeneous spaces 5. Conditions for a sharp bound 6. Stationary points 7. Numerical results 8. Uniqueness Appendix A. ...
