An incandescent lamp color light emitting diode lamp comprises a semiconductor blue light emitting diode chip having a center emission wavelength in a range of from 400 nm to 480 nm and a phosphor that absorbs light emitted from the diode chip to emit light having a different wavelength than the light emitted from the diode chip. The phosphor is represented by a general formula of Mp(Si, Al)12(O, N)16:Eu2+q. The main phase is an α-SiAlON phosphor having an α SiAlON structure, wherein M is at least one element of Ca, Y, Mg, Li, Sc, Pr, Nd, Pm, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Sr and p is from 0.75 to 1.0; and q is between 0.02 and 0.09. The diode lamp emits light having an emission color produced by a mixture of the light emitted from the semiconductor blue light emitting and the light emitted from the α-SiAlON. The chromaticity range thereof falls within the range defined by chromaticity coordinates (x, y) of (0.4775, 0.4283), (0.4594, 0.3971), (0.4348, 0.4185), and (0.4214, 0.3887) on the XYZ chromaticity diagram.

An objective of the present invention is to provide antibodies that recognize HLA class I and have significant cell death-inducing activity. To achieve the above objective, first, the present inventors immunized mice with soluble HLA-A to which a FLAG tag is attached. Four days after the final immunization, spleen cells from the mice were fused with mouse myeloma cells. Then, hybridoma screening was carried out using the cell aggregation-inducing activity and cell death-inducing activity as an index. Thus, the monoclonal antibody F17B1 that has strong cell death-inducing activity was selected. The sequences of the H chain and L chain variable regions of the mouse monoclonal antibody F17B1 were determined to humanize this antibody. Then, the humanized anti-HLA class I antibody H2-G1d_L1-k0 was assessed for cell death induction. The result showed that H2-G1d_L1-k0 suppressed the growth of the IM9 cell line in a concentration dependent manner.
摘要:
A novel gene, dubbed “YS68”, involved in primitive hematopoiesis was successfully isolated from cDNA derived from mouse yolk sacs. In addition, a human gene corresponding to this gene was successfully isolated. Expression characteristics of these genes suggested their involvement in primitive hematopoiesis. The proteins of this invention and genes encoding the proteins may be utilized as tools for drug development against diseases, such as hematological disorders.
