Lysate Details for LAG-3

Protein State


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 manufactured by and sold under license from OriGene Technologies and its use is limited solely for research purposes.

FAQs for LAG-3 Lysate (NBP2-04223). (Showing 1 - 4 of 4 FAQ).

  1. What is the concentration of your biotin conjugated LAG-3 antibody?
    • We actuall do not determine the concentration of our conjugated antibodies but they are usuall 80-100% the concentration of the base product, so the concentration should be at least 0.8 mg/ml.
  2. Can this LAG-3 antibody be used in ELISA?
    • We have not validated this particular LAG-3 antibody for ELISA in mouse; however, it has been cited as being used as a detection antibody in a publicatoin (PMID 15946792).
  3. I'm using your LAG-3 antibody in western blot but the observed band is a different size than the predicted band size, do you know what the bands are?
    • There are several alternative splice varients of LAG-3 that could explain the different sized proteins stained by the LAG-3 antibody. It is also believed that there are two secreted forms of LAG-3, one that is about 36 kDa and another at 52 kDa.
  4. Is this LAG-3 antibody offered in a smaller size that is less expensive?
    • We do not offer a sample size for this particular LAG 3 antibody but we do offer another, AF3329, in a 25 ug sample size.
