Bulk anti-IFN beta In Vivo Antibody – Low Endotoxin (HDB-4A7)
ichorbio’s anti-IFN beta In Vivo Antibody – Low Endotoxin (HDB-4A7) is manufactured in a cGMP compliant. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio: the best antibodies for in vivo research.
ichorbio’s HDB-4A7 in vivo antibody is available in the following bulk sizes:
1mg, 5mg, 25mg, 50mg and 100mg
ichorbio regularly manufactures multi-gram amounts of our anti-interferon beta HDB-4A7 clone – please contact us for pricing.

Anti-IFN beta In Vivo Antibody – Low Endotoxin (HDB-4A7) recognizes an epitope on Mouse IFN-beta and binds specifically to murine IFNbeta and does not bind murine IFNg or several different IFNa species (a-1,4,5 or 13); HDb-4A7 binds both recombinant and natural forms
This antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

We use the IMPACT test generated by IDEXX Laboratories to guarantee our Ultra Low Endotoxin antibodies are pathogen free. Our mouse antibodies are tested for:
Mouse hepatitis virus
Pneumonia virus of mice
Minute virus of mice
Mouse parvovirus (MPV1-5)
Theiler’s murine encephalomyelitis virus
Lymphocytic choriomeningitis virus
Lactate dehydrogenase-elevating virus
Mouse adenovirus (MAD1, MAD2)
Mouse thymic virus
Corynebacterium spp. (HAC2)
anti-IFN beta In Vivo Antibody – Low Endotoxin (HDB-4A7) is stable when stored at 2-8°C. Do not freeze. For long term storage aseptically aliquot in working volumes without diluting and store at –80°C. Avoid Repeated Freeze Thaw Cycles.
Western Blot, Blocking, Functional Assays
Blocking: Blocks in vivo IFNb leading to increased the lethality of mice infected with West Nile Virus (WNV), similar to the susceptibility of IFNb-/- mice. Clone HDB-4A7 circulates with a half-life of ~ 14 days.
Each investigator should determine their own optimal working dilution for specific applications.
