Informations générales

KRAS, also called p21, is a member of the Ras superfamily of proteins. It is located on human chromosome 12, and contains four coding exons and a 5' non-coding exon (PMID: 12778136). KRAS is a membrane-anchored guanosine triphosphate/guanosine diphosphate (GTP/GDP)-binding protein and is widely expressed in most human cells. Like other members of the Ras family, the KRAS protein is a GTPase, and it is involved in intracellular signal transduction and mainly responsible for EGFR-signaling activation (PMID: 19117687). KRAS mutations have been found in various malignancies, including lung adenocarcinoma, mucinous adenoma, ductal carcinoma of the pancreas and colorectal carcinoma.

Christopher (Verified Customer) (12-11-2018)

Antibody is much better than comparable antibodies. Because of weak expression an very low differences between K-Ras/H-Ras/N-Ras it's quite difficult to detect only K-Ras in a specific way. That is also the problem of this antibody. Please look at my attached blot. 1. Fermentas prestained marker2. PANC-1 whole cell lysate3. PANC-1/EGFP-K-Ras4. HEK293/EGFP-K-Ras5. HEK293/EGFP-H-Ras6.HEK293/EGFP-N-Ras7. 20 ng recombinant K-Ras (His-tagged)Unfortunately, K-Ras (12063-1-AP) recognizes also H-Ras and in less amounts N-Ras. Looking at endogenous K-Ras detection, you have to keep in mind, that the upper band is K-Ras and the lower one H-Ras. Because of the fact, that N-Ras is only recognized in very low amounts (probably almost not on endogenous level) this antibody is great detecting endogenous K-Ras in whole cell lysates with some little problems
