Abstract:
The present invention is a method for a biochip detecting limited cells. The present invention comprises steps of: obtaining a nylon membrane chip having required nucleotide fragments arranged in a dot matrix way by using a manual spotter; naturally drying by heat and fixing the nucleotide fragments on the nylon membrane chip by a rapid nucleic acid cross-linker when preparing a chip; collecting some normal whole blood to be linearly amplified; synthesizing required amount of cDNA by a reverse transcription to obtain a marker as a probe; processing labeling, hybridization and post-hybridization to the chip and the marker; processing chemical color reaction; and automatically analyzing the result image after the chemical color reaction. Accordingly, a gene biochip operation technology platform with low cost, easy operation and high efficiency is obtained. And so the functions and the applications of the gene biochip can be effectively worked out and the practical applications of the gene biochip on related fields can be conclusively popularized.
Abstract:
A novel anti-polyethylene glycol monoclonal antibody and its preparation are disclosed. Such an antibody can be used for determining polyethylene glycol concentration in vitro or accelerating the clearance of a polyethylene glycol containing compound from the blood circulation in the human body thereby reducing the toxicity associated with the polyethylene glycol containing conjugate. The antibody is particularly useful in cancer therapy where the therapeutic agent is selectively delivered to the tumor by increasing the tumor/blood ratio of the polyethylene glycol containing compound.
Abstract:
The present invention provides an auto-developing and regularly-weighted protein molecular weight marker kit, comprising: (a) a plurality of recombinant proteins having formula (I), (B)m-A-(C)n (I), wherein A is a polypeptide of SEQ ID NO: 1, B and C are independently any mutually identical or different polypeptides with the value of molecular weight being a multiple of 5, and m and n is independently 0 or any integer larger than 0; and (b) one or more solvents for stabilizing the recombinant proteins. The present invention also provides a method for preparing the auto-developing and regularly-weighted protein molecular weight marker kit.

Abstract:
A recombinant DNA construct is provided and includes a first DNA fragment encoding a β-glucuronidase and a second DNA fragment encoding a membrane anchoring domain. The β-glucuronidase may be a human β-glucuronidase or a mouse β-glucuronidase. In one embodiment, an expression vector for delivering a gene of interest or portion thereof into a host cell includes a DNA sequence for the gene of interest, a first DNA fragment encoding a β-glucuronidase, and a second DNA fragment encoding a membrane anchoring domain. In another embodiment, a method of introducing a gene of interest or portion thereof into a host cell is provided, including introducing into the host cell a recombinant DNA construct.
Abstract:
A method for detecting cancer cells. A chemical luminescence reaction is used to obtain a result image. The result image is analyzed through a weighting process to a value of each gene. By doing do, a cancer can be precisely diagnosed.
Abstract:
In this invention, anti-PEG antibodies or anti-methoxyl-PEG (anti-CH3O-PEG) antibodies were expressed on cell surface which can collocate with a biotinylated anti-PEG antibody (AGP4-Biotin) or biotinylated PEG (PEG-Biotin) to develop a cell-based sandwich ELISA or a cell-based competition ELISA, respectively. Both of these two methods could sensitively quantify free PEG and PEG-modified macromolecules (proteins, nanoparticles and liposomes) as sensitive as nano-gram level.
