Description : | CA19-9 played an important role in many functions. |
Source : | E. coli |
Species : | Human |
Tag : | His |
Form : | PBS, pH7.4, containing 0.01% SKL, 1mM DTT, 5% Trehalose and Proclin300. |
Molecular Mass : | 39.7kDa |
Identity : | Reconstitute in PBS (pH7.4) to a concentration of 0.1-1.0 mg/mL. Do not vortex. |
Protein length : | Arg35~Thr361 |
Endotoxin : | <1.0EU per 1µg (determined by the LAL method) |
Purity : | > 95% |
Applications : | Positive Control; Immunogen; SDS-PAGE; WB. If bio-activity of the protein is needed, please check active protein |
Stability : | The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 centigrade for 48h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition. |
Storage : | Avoid repeated freeze/thaw cycles. Store at 2-8 centigrade for one month. Aliquot and store at -80 centigrade for 12 months. |
Reconstitution : | Reconstitute in PBS or others |

Ask a questionYour batch is at a concentration of 0.3mg/ml. You can use sterile water or PBS to dilute it to the ideal condition.
Some non-malignant conditions, like pancreatitis and liver disease, can elevate CA19-9.
CA19-9 is a carbohydrate antigen present on certain protein and lipid molecules in cells.
Effective treatments may reduce CA19-9 levels, correlating with tumor size or activity.
CA19-9 is more specific than sensitive; it's often used alongside other tests and markers.
CA19-9 is often elevated in certain cancers, aiding in diagnosis and monitoring.
CA19-9 lacks absolute specificity and sensitivity, so other diagnostic tools are crucial for accurate assessment.
It's particularly associated with pancreatic, liver, and colorectal cancers.
