詳細介紹

Recombinant Human IFN-r 貨號:300-02 細胞因子 

 

細胞因子受體的結(jié)構(gòu)和分類:根據(jù)細胞因子受體cDNA序列以及受體胞膜外區(qū)氨基酸序列的同源性和結(jié)構(gòu)征，可將細胞因子受體主要分為四種類型：免疫球蛋白超家族（IGSF）、造血細胞因子受體超家族、神經(jīng)生長因子受體超家族和趨化因子受體。

 

Catalog Number:
300-02
Synonyms:
Immune Interferon, type II interferon, T cell interferon, MAF
Description:
IFN-γ is an acid-labile interferon produced by CD4 and CD8 T lymphocytes as well as activated NK cells. IFN-γ receptors are present in most immune cells, which respond to IFN-γ signaling by increasing the surface expression of class I MHC proteins. This promotes the presentation of antigen to T-helper （CD4+） cells. IFN-γ signaling in antigen-presenting cells and antigen-recognizing B and T lymphocytes regulate the antigen-specific phases of the immune response. Additionally, IFN-γ stimulates a number of lymphoid cell functions including the anti-microbial and anti-tumor responses of macrophages, NK cells, and neutrophils. Human IFN-γ species-specific and is biologically active only in human and primate cells. Recombinant human IFN-γ is a 16.7 kDa protein containing 143 amino acid residues.
