PMEL p.Leu18del dilutes coat color of Kumamoto sub-breed of Japanese Brown cattle.

Background: Coat color is important for registration and maintenance of livestock. Standard coat color of Kumamoto sub-breed of Japanese Brown cattle is solid brown, but individuals with diluted coat color have been observed recently. In this study, we attempted to identify polymorphism(s) responsible for coat color dilution by whole genome analysis.

Selection and analysis of anti-cancer antibodies for cancer therapy obtained from antibody phage library.

The search for effective antibodies (Ab) for curable cancer immunotherapy has been a quest of many research groups in order to find an effective target that exists on the cancer cell surface. So far there have been no conclusive answers to shed light on the search. This study therefore aimed to bridge the gap of cancer therapy.

Methods for comprehensive identification of membrane proteins recognized by a large number of monoclonal antibodies.

In order to isolate monoclonal antibodies (mAbs) that bind to tumor-associated antigens (Ags) we developed the following strategy. Using the phage-display Ab library we isolated a large number of mAbs that bind to the surface of human tumor cells. The mAbs were individually screened by immunostaining, and clones that preferentially and strongly stained the malignant cells were chosen.

Frequent overexpression of CADM1/IGSF4 in lung adenocarcinoma.

We reported comprehensive screening for antigens (Ags) overexpressed on various carcinomas via isolation of human monoclonal antibodies (mAbs) that may be therapeutic in a previous paper (Proc. Natl. Acad.

Isolation of antigen/antibody complexes through organic solvent (ICOS) method.

We developed a method termed ICOS (isolation of antigen-antibody complexes through organic solvent) for comprehensive isolation of monoclonal antibodies (mAbs) bound to molecules on the cell surface. By mixing a large number of phage particles of an antibody (Ab) library with living cells, antigen (Ag)-Ab complexes were formed on the cell surface. The mixture was overlaid on organic solution in a tube and subjected to centrifugation.

Weight loss and isotopic shifts for water drops frozen on a liquid nitrogen surface.

A liquid nitrogen freezing method was used to collect raindrops for the determination of isotope-size distribution. Water drops that fall onto a surface of liquid nitrogen stay suspended for 10 to 20 s, until their temperature reaches the Leidenfrost point (126 K). As their temperature falls to the freezing point, they release their heat by thermal conduction.

Comprehensive screening for antigens overexpressed on carcinomas via isolation of human mAbs that may be therapeutic.

Although several murine mAbs that have been humanized became useful therapeutic agents against a few malignancies, therapeutic Abs are not yet available for the majority of the human cancers because of our lack of knowledge of which antigens (Ags) can become useful targets. In the present study we established a procedure for comprehensive identification of such Ags through the extensive isolation of human mAbs that may become therapeutic. Using the phage-display Ab library we isolated a large number of human mAbs that bind to the surface of tumor cells.
