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.

Sophy (Verified Customer) (12-22-2022)
I have tried the KRas antibody from a lot of companies and this one from proteintech definitely has been working the best for me.
Jonas (Verified Customer) (07-29-2022)
Antibody works as expected, dilution with 1:2000 was perfect and could even be increased to 1:5000; delivery was very fast, would recommend!!
Usman Shah (Verified Customer) (11-29-2021)
Enables specific detection of KRAS in WBs.
Kishor (Verified Customer) (12-13-2018)
I am very much satisfied with this antibody. I got good results for cells and rat liver tissue protein.
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
