Background Information
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.

Reviews
The reviews below have been submitted by verified Proteintech customers who received an incentive forproviding their feedback.
FH 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.
|
FH 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!!
 |
FH Usman Shah (Verified Customer) (11-29-2021) | Enables specific detection of KRAS in WBs.
|
FH 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.
|
FH 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
