Q: I would like to buy antibodies APOA4 (apolipoprotein AIV) for the cows (to western blot). I know that You don't have the antibodies for this species. Could You propose the best atibodies which I could test (use) in my experiment?

A: All eight of our APOA4 antibodies were raised against the human protein, and all of them have currently only been tested against human samples. I ran an alignment for you and found that there is a 77% sequence homology between human and bovine APOA4, so it is possible that the antibodies raised against human APOA4 may recognise the bovine protein. Should you wish to try any of our antibodies with your samples, you may be interested in our Innovator's Reward Program, which allows you to try our primary antibodies in an untested species or application without the financial risk of failure. To participate you simply complete an online review with an image, detailing the positive or negative results of your study, and in return you receive a discount voucher for 100% of the purchase price of the reviewed product.

Product Summary for Apolipoprotein A-IV/ApoA4 Overexpression Lysate

Apolipoprotein A-IV/ApoA4 Transient Overexpression Lysate

Expression Host: HEK293T

Plasmid: RC222222

Accession#: NM_000482

Protein Tag: C-MYC/DDK

You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.

Product Specifications

Application Notes

This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.

Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.

Theoretical MW

43.3 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background: Apolipoprotein A-IV/ApoA4

Apoliprotein (apo) A-IV gene contains 3 exons separated by two introns. A sequence polymorphism has been identified in the 3'UTR of the third exon. The primary translation product is a 396-residue preprotein which after proteolytic processing is secreted its primary site of synthesis, the intestine, in association with chylomicron particles. Although its precise function is not known, apo A-IV is a potent activator of lecithin-cholesterol acyltransferase in vitro.

Product Specific Notices for Apolipoprotein A-IV/ApoA4 Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Lysates are guaranteed for 6 months from date of receipt.
