Animal-Free Activin A Protein, Human/Mouse/Rat (His)

Cat. No.: HY-P700159AF
COA Handling Instructions

The INHBA protein plays a key role in regulating pituitary function by regulating follicle-stimulating hormone secretion together with activin. Its broad effects span a variety of physiological processes, including hormone secretion, germ cell development, erythrocyte differentiation, insulin secretion, nerve cell survival, embryonic development, and bone growth, depending on unique subunit composition. Animal-Free Activin A Protein, Human/Mouse/Rat (His) is the recombinant human, rat, mouse-derived animal-FreeActivin A protein, expressed by E. coli , with C-His labeled tag. The total length of Animal-Free Activin A Protein, Human/Mouse/Rat (His) is 116 a.a., with molecular weight of ~13.9 kDa.

Animal-free recombinant proteins offer high consistency and stability, whithout using or contacting of any animal-derived materials and reagents.

Background

INHBA protein assumes a pivotal role in the intricate regulation of pituitary gland function, contributing to the opposing dynamics of inhibiting and activating follitropin secretion alongside activins. The expansive influence of inhibins and activins, with INHBA as a central player, spans a spectrum of physiological processes, including hypothalamic and pituitary hormone secretion, gonadal hormone secretion, germ cell development and maturation, erythroid differentiation, insulin secretion, nerve cell survival, embryonic axial development, and bone growth, contingent upon their unique subunit compositions. Notably, inhibins, such as Inhibin A and Inhibin B, emerge as counterparts opposing the functions of activins. Structurally, INHBA exists in a dimeric form, intricately linked by one or more disulfide bonds, representing a homodimer of beta-A subunits. The diversity of activins, encompassing Activin A, Activin B, and Activin AB, further emphasizes their specific subunit compositions, influencing interactions with regulatory proteins like FST and FSTL3. This intricate interplay underscores INHBA's central role in orchestrating a finely tuned regulatory network governing diverse physiological functions.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
