Scientific context
Chk1 is a protein-serine/threonine kinase required for checkpoint-mediated cell cycle arrest. It also subsequently activates DNA repair (i.e. homologous recombination) by phosphorylating RAD51 or FANCE in response to the presence of damage or unreplicated DNA. It regulates cell cycle progression via several mechanisms: 1) phosphorylation of certain proteins such as CDC25A, CDC25B and CDC25C, promoting their degradation; 2) phosphorylation and activation of p53; 3) phosphorylation and inactivation of TLK1, which consequently prevents TLK1-dependent phosphorylation of chromatin assembly factor ASF1A; 4) phosphorylation of histones and regulating transcription of genes involved in cell-cycle progression regulation; 5) phosphorylation of RB1 to promote its interaction with E2F transcription factors and subsequent cell cycle arrest

Description
This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided. Antibody for research use.

Test
StressMark antibodies supplies antibodies that are for research of human proteins.
-
Properties
Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.

About
Polyclonals can be used for Western blot, immunohistochemistry on frozen slices or parrafin fixed tissues. The advantage is that there are more epitopes available in a polyclonal antiserum to detect the proteins than in monoclonal sera. Rabbits are used for polyclonal antibody production by StressMark antibodies. Rabbit antibodies are very stable and can be stored for several days at room temperature. StressMark antibodies adds sodium azide and glycerol to enhance the stability of the rabbit polyclonal antibodies. Anti-human, anti mouse antibodies to highly immunogenic selected peptide sequences are" monoclonal like" since the epitope to which they are directed is less than 35 amino acids long.
