Protein Length
Full Length
Tag Info
C-terminal 10xHis-tagged
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer
Lyophilized from a 0.2 μm filtered PBS, 6% Trehalose, pH 7.4
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Lead Time
3-7 business days
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, storage temperature and the stability of the product itself. Generally, the shelf life of lyophilized form is 6 months at -20°C/-80°C from the date of receipt.

Description
KAAG1, a kidney-associated antigen implicated in renal cell carcinoma and other malignancies, remains challenging to produce in functional form due to its small size and potential aggregation. This full-length construct (aa 1–84) demonstrates robust antibody-binding activity with an EC50 of 4.924–6.034 ng/mL in functional ELISA, confirming proper folding and epitope accessibility essential for immunoassay development and antibody screening workflows. The baculovirus expression system yields protein exceeding 90% purity as determined by SDS-PAGE, with endotoxin levels below 1.0 EU/μg, meeting the quality thresholds commonly required for antibody validation studies, ELISA standard curve generation, and binding competition assays in cancer biomarker research. The C-terminal 10×His tag facilitates straightforward purification while preserving the native N-terminus critical for antibody recognition, making this reagent appropriate for developing diagnostic tools targeting KAAG1 in renal and other cancer contexts.
