IgA antibody | K61 1B4
Mouse anti Pig IgA antibody, clone K61 1B4 (MCA638GA) used for the measurement of ova specific IgA levels in serum by ELISA.
Image caption:
OVA-specific antibody-mediated immune responses in serum from newborn piglets gavaged with OVA then i.p. immunized with OVA at four weeks of age. Piglets (n = 5/group) were gavaged and i.p. immunized as described in Figure 1. Control newborn piglets were not gavaged or immunized with OVA. We measured serum anti-OVA IgM (A), IgA (B), IgG (C), IgG1 (D) and IgG2 (E) production on day 28, day 42 and day 49 after birth. Each data point represents an individual animal and median values are indicated by horizontal lines. *p <0.05., **p <0.01.

Mouse anti Pig IgA antibody, clone K61 1B4 (MCA638) used for the measurement of ova specific IgA levels in lung lavages by ELISA.
Image caption:
OVA-specific antibody-mediated immune responses in lung washes from newborn piglets gavaged with OVA then i.p. immunized with OVA at four weeks of age. Piglets (n = 5/group) were gavaged and i.p. immunized as described in Figure 1. Control newborn piglets were not gavaged or immunized with OVA. Lung lavages were collected four weeks post i.p. immunization and OVA-specific serum IgM (A), IgA (B), IgG (C), IgG1 (D), and IgG2 (E) titres were measured. ELISA titres are expressed as the reciprocal of the highest dilution resulting in a reading of two standard deviations above the negative control. Each data point represents an individual animal and median values are indicated by horizontal lines. *p <0.05, **p <0.01.

Mouse Anti Pig IgA antibody, clone K61 1B4 recognizes porcine immunoglobulin (Ig) alpha chain. No cross-reactivity is observed with either porcine IgM or IgG.
It has been suggested that pigs possess two subclasses of IgA, referred to as either IgA1 and IgA2 similar to the human IgA subclasses. More recent research indicates that these are allotypic variants and described as IgAa and IgAb (Navarro et al. 2000). Research undertaken in connection with porcine IgA response to Foot and Mouth disease (Pacheco et al. 2010) has demonstrated that clone K61 1B4 recognises both IgAa and IgAb allotypes.
IgA is the dominant immunoglobulin found in surface secretions where its role is in the protection of body surfaces. High levels of IgA may be detected in tracheal secretions, saliva, intestinal fluid and urogenital tract secretions. The primary function of IgA is to prevent adherence of bacteria and virus to epithelial surfaces. IgA may also act within epithelial cells where it has a role in interrupting viral replication.
