摘要:
Disclosed are: a method for identifying/analyzing a gene for an antibody in one cell derived from a human; a technique for producing an antibody derived from an identified one B cell; and others. A gene for an antibody specific to a melanoma antigen is analyzed/identified at a one-cell level by using an immortalized B cell produced from peripheral blood monocytes from a melanoma patient or a primary B cell included in the peripheral blood monocytes. It is found that B cells capable of producing a specific antibody can be separated on one cell by one cell basis by staining the B cells with a GST-labeled melanoma-specific cancer antigen MAGE1, an Alexa-labeled anti-GST antibody and a PE-labeled anti-human IgG antibody and carrying out the single cell sorting of the stained B cells. Further, a practical technique for extracting total RNA from the separated one B cell and cloning a gene for a specific antibody into the total RNA efficiently can be established.

摘要:
It is to provide an agent for preventing and treating skin aging, or an agent for treating skin scar that can exert a sufficient effect. An agent for preventing and treating skin aging comprising bFGF for treating aging of the skin that is administered intradermally or subcutaneously, or an agent for treating skin scar comprising bFGF for treating scar of skin that is administered intradermally or subcutaneously is utilized. Preferred examples of aging of skin include skin wrinkle, pigmented spot, sagging skin, rough skin, skin thinning, decrease of skin viscoelasticity, etc., and preferred examples of scar include keloid, hypertrophic scar, scar contracture, etc.
摘要:
The invention relates to a method of aiding the diagnosis of a human immunodeficiency virus infection in a subject, said method comprising (i) providing a sample from the subject (ii) determining the level of ps20 in said sample (iii) comparing the level of ps20 of (ii) with the level of ps20 in an uninfected reference sample, wherein a higher level of ps20 in the sample from the subject compared to the uninfected reference sample indicates an increased likelihood of human immunodeficiency virus infection in said subject. The invention also relates to methods for assessing susceptibility of a subject to human immunodeficiency virus infection. Most suitably the ps20 level is determined via binding by an anti-ps20 antibody such as the IG7 antibody. The invention also relates to kits for use in said methods.

摘要:
It is to provide a method for determining allergic diseases with a high sensitivity and accuracy which enables multilateral and global analysis with a minute amount of sample, even using body fluid other than blood such as saliva, nasal discharge and tears as a sample, particularly by suppressing nonspecific reaction as much as possible. A chemically modified diamond/DLC (Diamond-like Carbon) chip is activated with a reacting reagent, a coupling reaction with a peptide comprising allergen or allergen epitope is conducted, and a sample such as saliva, tears, and nasal discharge which has undergone pressure filtration with a low protein-adsorbing filter, is contacted with an allergen determination chip to which washing and blocking operations have been performed on unreacted active groups, and an allergen recognizing antibody in the sample captured by the allergen determination chip is detected by immunoassay using a labeled secondary antibody, wherein a glycine-containing solution is used for a washing solution and/or blocking solution used in the washing and blocking operations, is used.
摘要:
Peptide-based anti-influenza formulations against influenza are disclosed. The peptides are derived from influenza-based epitopes. The formulations are based on peptide mixtures which may be formulated so that variability is present at particular residues. The formulations can be used to prepare vaccines for preventing influenza, particularly avian influenza.
