Validation Images

HA-tagged fusion proteins were expressed in NIH/3T3 cells. Whole cell lysates were separated by SDS-PAGE and the tagged protein detected using anti HA-tag antibody ABIN2443910 diluted 1:600. Expected molecular mass of the fusion proteins were approximately 26kDa (A.) and 43kDa (B.) respectively. The left lane corresponds in both blots A. and B. to the pellet, the right to the supernatant after centrifugation. Exposition time for image capture on X-ray films: 1min (A.) and 30min (B.). For C., samples were prepared as for B. but the anti HA-tag antibody ABIN2443910 was diluted 1:1000. Exposure time: 15min.

Antigen: HA-Tag

Lot Number: 16631508212-P

Method validated: Immunocytochemistry

Positive Control: HA-fusion proteins transiently expressed in NIH/3T3 cells

Notes: Passed, regarding sensitivity and specificity. The antibody specifically detects the HA-fusion protein in immuno-cytochemical experiments. No obvious background staining was found.

Validation Images

HA-tagged fusion proteins were expressed in NIH/3T3 cells. The protein of interest is expected to localize to the nuclear membrane and the cytoplasm. A. The fusion protein was revealed via its HA-tag at the nuclear membrane and in the cytoplasm using ABIN2443910 (green; DAPI counterstain in blue). B. Co-staining of the fusion protein with using using anti-HA tag antibody ABIN2443910 (green) and an anti-myc-tag antibody (red; unspecific background staining caused by the transfection reagent). DAPI staining was used to visualize the nucleus (blue).

Experimental Notes: none

Handling

Format: Lyophilized

Reconstitution: If reconstituted with deionized water in 100 μL: WB 1:1000-3,000, IHC 1:500-2,000. Optimal dilution has to be determined by the user.

Buffer: Lyophilized protein G purified in PBS pH 7.4

Preservative: Without preservative

Storage: 4 °C,-20 °C,-80 °C

Storage Comment: Lyophilized antibodies can be kept at 4°C for up to 3 months and should be kept at -20°C for long-term storage (2 years). To avoid freeze-thaw cycles, reconstituted antibodies should be aliquoted before freezing for long-term (1 year) storage (-80°C) or kept at 4°C for short-term usage (2 months). For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made with the assay buffer. After the maximum long-term storage period (2 years lyophilized or 1 year reconstituted) antibodies should be tested in your assay with a standard sample to verify if you have noticed any decrease in their efficacy. To limit antibody loss or degradation, BSA (final concentration 1%) and sodium azide (final concentration 0.02%) can be added to the suggested first dilution. It is important to first verify if those preservatives are compatible with your assay.

Expiry Date: 24 months

Target Details for HA-Tag

Target: HA-Tag

Alternative Name: HA Tag

Target Type: Tag

Background: Epitope tags have application in the labeling, isolation and detection of proteins using immunoblotting, Immunoprecipitation and immunostaining techniques. Epitope tags can be used, by affinity chromatography, to separate recombinant, overexpressed protein from wild-type protein expressed by the host organism. Due its small size the protein's biochemical properties seem not to be affected by the tag protein. Human influenza hemagglutinin (HA) is a surface glycoprotein required for the infectivity of human by the virus. The HA tag corresponds to the amino acids 98-106 (YPYDVPDYA) of the HA protein. It has been extensively used as a general epitope tag in expression vectors. Many recombinant proteins have been engineered to express the HA tag.
