High-throughput antibody isolation

Current Opinion in Chemical Biology, 2001
To define the proteome of an organism, there is a need for robust and reproducible methods for the quantitative detection of all the polypeptides in a cell. High-density arrays of receptors specific for each of the polypeptides in a complex sample hold great promise for the analysis of complex protein mixtures.

Isolation and the high/low hierarchy

Archive for Mathematical Logic, 2002
A subset \(D\) of \(\omega\) is called a d.c.e. (difference of c.e. sets) if there are c.e. (computably enumerable) sets \(A_0\) and \(A_1\) such that \(D=A_0 -A_1\). A d.c.e. degree \(\mathbf d\) is called isolated by a c.e. degree \(\mathbf b\) if \({\mathbf b}

Isolation of liver polyribosomes in high yield

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1967
Abstract Addition of low-molecular-weight ribonucleic acid during tissue homogenization was found to be effective in inhibiting ribonuclease degradation of polyribosomes. In this way it is possible to use the total cytoplasmic fraction and recover a much higher yield of polyribosomes than is normally obtained from the post-mitochondrial supernatant ...

High-Energy Isolated Attosecond Pulses

International Conference on Ultrafast Phenomena, 2010
We demonstrate the generation of isolated sub-160-attosecond pulses with on-target pulse-energy of a few nanojoules, thus showing a pulse-energy enhancement from one to three orders of magnitude compared with the generating methods demonstrated so far.

Isolation of High Oxygen Affinity Hfmoclobins

Hemoglobin, 1977
This paper describes a method for isolating high oxygen affinity hemoglobins. It involves the selective derivatisation of the cysteine residue at position 93 in the beta chain. The iodoacetamide derivative of the high oxygen affinity hemoglobin was separated from the more negatively charged iodoacetic acid derivative of HbA on DEAE-Sephadex. The method

High performance rotational vibration isolator

Review of Scientific Instruments, 2013
We present a new rotational vibration isolator with an extremely low resonant frequency of 0.055 ± 0.002 Hz. The isolator consists of two concentric spheres separated by a layer of water and joined by very soft silicone springs. The isolator reduces rotation noise at all frequencies above its resonance which is very important for airborne mineral ...

High-isolation optical isolator using a BiCaInVIG single crystal

Applied Optics, 1992
To the best of our knowledge this is the first time a new optical isolator has been developed that uses BiCaInVIG, a non-rare-earth iron garnet. The device has high isolation > 40 dB with an insertion loss of 1.0 dB at 1.3-microm wavelength and > 43 dB with 1.1 dB at 1.52-microm wavelength, including Fresnel reflection losses of ~0.8 dB for two ...

Device isolation in high-density LOCOS-isolated CMOS

IEEE Transactions on Electron Devices, 1987
Leakage paths between n- and p-channel devices in high packing density CMOS circuits fabricated using standard LOCOS isolation are investigated. Experimental results and the results of two-dimensional numerical modeling are presented for both a conventional n-well and a retrograde n-well technology.
