||Checkpoint homolog CHK2 is an important cell cycle checkpoint regulator. The protein is rapidly activated by phosphorylation in response to DNA damage and to replication block. When activated, CHK2 is known to prevent entry into mitosis and has been shown to regulate the tumor suppressor protein p53, leading to cell cycle arrest in G1. At least 12 isoforms are produced by alternative splicing.

||A synthetic peptide (FSEHRTQVSLKDQIT) corresponding to a region (427-441) from human Checkpoint homolog CHK2. To enhance the immunological response, this peptide was coupled to carrier protein BSA.
||Serine/threonine-protein kinase Chk2; EC 22.214.171.124; Cds1; CHEK2; CHK2; RAD53;
||Affinity purified on antigen column
||Western Blotting (WB). A concentration of 0.75 ug/mL is recommended for WB. Human Checkpoint homolog CHK2 (isoform 1) has a predicted length of 543 residues and MW of 61 kDa. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
||The specificity of this antibody has been confirmed by WB against the antigen.
||Human; rat; predicted to react with mouse due to sequence homology;
||If you wish to use this product in a species other than those specified here and want to determine the amino acid sequence homology between the immunogen and the corresponding protein in that species, simply copy the amino acid sequence for this immunogen and test it on the BLAST database that you can access through the link below. Please note that antibodies raised against synthetic peptides are quite often very specific for that peptide. What this means in practise is that a single amino acid difference may be enough to restrict the specificity to a particular molecule.
The BLAST database can also be used to compare any amino acid sequence between species and between protein. The full amino acid sequence of the target protein can be found by following the link in the Accession field. You can then search any amino acid sequence in the target protein using the BLAST database. When selecting a sequence to search, please choose carefully, as the sequence you choose may be a precursor rather than the mature protein for example.
||Lyophilised with 5mg BSA, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg Thimerosal, 0.05mg NaN3
||Reconstitute in 100 uL of sterile distilled water to achieve an antibody concentration of 1 mg/mL. Centrifuge to remove any insoluble material.
||At least 12 months after purchase at 2-8C (lyophilized formulations). After reconstitution, aliquot and store at -20C for a higher stability. Avoid freeze-thaw cycles.
